Buckminster Fuller’s Dymaxion Sleep Plan: He Slept Two Hours a Day for Two Years & Felt “Vigorous” and “Alert”

One poten­tial draw­back of genius, it seems, is rest­less­ness, a mind per­pet­u­al­ly on the move. Of course, this is what makes many cel­e­brat­ed thinkers and artists so pro­duc­tive. That and the extra hours some gain by sac­ri­fic­ing sleep. Voltaire report­ed­ly drank up to 50 cups of cof­fee a day, and seems to have suf­fered no par­tic­u­lar­ly ill effects. Balzac did the same, and died at 51. The caf­feine may have had some­thing to do with it. Both Socrates and Samuel John­son believed that sleep is wast­ed time, and “so for years has thought grey-haired Richard Buck­min­ster Fuller,” wrote Time mag­a­zine in 1943, “futu­rif­ic inven­tor of the Dymax­ion house, the Dymax­ion car and the Dymax­ion globe.”

Engi­neer and vision­ary Fuller intend­ed his “Dymax­ion” brand to rev­o­lu­tion­ize every aspect of human life, or—in the now-slight­ly-dat­ed par­lance of our obses­sion with all things hacking—he engi­neered a series of rad­i­cal “life­hacks.” Giv­en his views on sleep, that seem­ing­ly essen­tial activ­i­ty also received a Dymax­ion upgrade, the trade­marked name com­bin­ing “dynam­ic,” “max­i­mum,” and “ten­sion.” “Two hours of sleep a day,” Fuller announced, “is plen­ty.” Did he con­sult with spe­cial­ists? Med­ical doc­tors? Biol­o­gists? Noth­ing as dull as that. He did what many a mad sci­en­tist does in the movies. (In the search, as Vin­cent Price says at the end of The Fly, “for the truth.”) He cooked up a the­o­ry, and test­ed it on him­self.

“Fuller,” Time report­ed, “rea­soned that man has a pri­ma­ry store of ener­gy, quick­ly replen­ished, and a sec­ondary reserve (sec­ond wind) that takes longer to restore.” He hypoth­e­sized that we would need less sleep if we stopped to take a nap at “the first sign of fatigue.” Fuller trained him­self to do just that, for­go­ing the typ­i­cal eight hours, more or less, most of us get per night. He found—as have many artists and researchers over the years—that “after a half-hour nap he was com­plete­ly refreshed.” Naps every six hours allowed him to shrink his total sleep per 24-hour peri­od to two hours. Did he, like the 50s mad sci­en­tist, become a trag­ic vic­tim of his own exper­i­ment?

No dan­ger of merg­ing him with a fly or turn­ing him invis­i­ble. The exper­i­men­t’s fail­ure may have meant a day in bed catch­ing up on lost sleep. Instead, Fuller kept it up for two full years, 1932 and 1933, and report­ed feel­ing in “the most vig­or­ous and alert con­di­tion that I have ever enjoyed.” He might have slept two hours a day in 30 minute incre­ments indef­i­nite­ly, Time sug­gests, but found that his “busi­ness asso­ciates… insist­ed on sleep­ing like oth­er men,” and wouldn’t adapt to his eccen­tric sched­ule, though some not for lack of try­ing. In his book Buck­y­Works J. Bald­win claims, “I can per­son­al­ly attest that many of his younger col­leagues and stu­dents could not keep up with him. He nev­er seemed to tire.”

A research orga­ni­za­tion looked into the sleep sys­tem and “not­ed that not every­one was able to train them­selves to sleep on com­mand.” The point may seem obvi­ous to the sig­nif­i­cant num­ber of peo­ple who suf­fer from insom­nia. “Bucky dis­con­cert­ed observers,” Bald­win writes, “by going to sleep in thir­ty sec­onds, as if he had thrown an Off switch in his head. It hap­pened so quick­ly that it looked like he had had a seizure.” Buck­min­ster Fuller was undoubt­ed­ly an unusu­al human, but human all the same. Time report­ed that “most sleep inves­ti­ga­tors agree that the first hours of sleep are the sound­est.” A Col­gate Uni­ver­si­ty researcher at the time dis­cov­ered that “peo­ple awak­ened after four hours’ sleep were just as alert, well-coor­di­nat­ed phys­i­cal­ly and resis­tant to fatigue” as those who slept the full eight.

Sleep research since the for­ties has made a num­ber of oth­er find­ings about vari­able sleep sched­ules among humans, study­ing shift work­ers’ sleep and the so-called “bipha­sic” pat­tern com­mon in cul­tures with very late bed­times and sies­tas in the mid­dle of the day. The suc­cess of this sleep rhythm “con­tra­dicts the nor­mal idea of a monopha­sic sleep­ing sched­ule,” writes Evan Mur­ray at MIT’s Cul­ture Shock, “in which all our time asleep is lumped into one block.” Bipha­sic sleep results in six or sev­en hours of sleep rather than the sev­en to nine of monopha­sic sleep­ers. Polypha­sic sleep­ing, how­ev­er, the kind pio­neered by Fuller, seems to gen­uine­ly result in even less need­ed sleep for many. It’s an idea that’s only become wide­spread “with­in rough­ly the last decade,” Mur­ray not­ed in 2009. He points to the redis­cov­ery, with­out any clear indebt­ed­ness, of Fuller’s Dymax­ion sys­tem by col­lege stu­dent Maria Staver, who named her method “Uber­man,” in hon­or of Niet­zsche, and spread its pop­u­lar­i­ty through a blog and a book.

Mur­ray also reports on anoth­er blog­ger, Steve Pavli­na, who con­duct­ed the exper­i­ment on him­self and found that “over a peri­od of 5 1/2 months, he was suc­cess­ful in adapt­ing com­plete­ly,” reap­ing the ben­e­fits of increased pro­duc­tiv­i­ty. But like Fuller, Pavli­na gave it up, not for “health rea­sons,” but because, he wrote, “the rest of the world is monopha­sic” or close to it. Our long block of sleep appar­ent­ly con­tains a good deal of “wast­ed tran­si­tion time” before we arrive at the nec­es­sary REM state. Polypha­sic sleep trains our brains to get to REM more quick­ly and effi­cient­ly. For this rea­son, writes Mur­ray, “I believe it can work for every­one.” Per­haps it can, pro­vid­ed they are will­ing to bear the social cost of being out of sync with the rest of the world. But peo­ple like­ly to prac­tice Dymax­ion Sleep for sev­er­al months or years prob­a­bly already are.

300,000 Wondrous Nature Illustrations Put Online by The Biodiversity Heritage Library

Are we tru­ly in the midst of a human-caused sixth mass extinc­tion, an era of “bio­log­i­cal anni­hi­la­tion”? Many sci­en­tists and pop­u­lar sci­ence writ­ers say yes, using terms like “Holocene” or “Anthro­pocene” to describe what fol­lows the Ordovi­cian, Devon­ian, Per­mi­an, Tri­as­sic, and Cre­ta­ceous peri­ods. Peter Bran­nen, the author of extinc­tion his­to­ry The Ends of the Earth has found at least one sci­en­tist who thinks the con­cept is “junk.” But Bran­nen quotes some alarm­ing sta­tis­tics. Chill­ing, even. “Until very recent­ly,” he writes, “all ver­te­brate life on the plan­et was wildlife. But astound­ing­ly, today wildlife accounts for only 3 per­cent of Earth’s land ani­mals; human beings, our live­stock, and our pets take up the remain­ing 97 per­cent of the bio­mass… almost half of the Earth’s land has been con­vert­ed into farm­land.”

This state of affairs does not bode well for the mil­lions of remain­ing species get­ting edged out of their envi­ron­ments by agribusi­ness and cli­mate change. We learn from extinc­tions past that the plan­et rebounds after unimag­in­able cat­a­stro­phe. Life real­ly does go on, though it may take mil­lions of years to recov­er. But the cur­rent forms of life may dis­ap­pear before their time. If we want to under­stand what is at stake besides our own frag­ile fos­sil-fuel-based civ­i­liza­tions, we need to con­nect to life emo­tion­al­ly as well as intel­lec­tu­al­ly. Short of globe-hop­ping phys­i­cal immer­sion in the Earth’s bio­di­ver­si­ty, we could hard­ly do bet­ter than immers­ing our­selves in the tra­di­tion of nat­u­ral­ist writ­ing, art, and pho­tog­ra­phy that brings the world to us.

The Bio­di­ver­si­ty Her­itage Library (BHL), an “open access dig­i­tal library for bio­di­ver­si­ty lit­er­a­ture and archives,” has for many years been mak­ing it easy for peo­ple to con­nect to nature through nature writ­ing and illus­tra­tion. On Flickr, you can find 319,000 care­ful­ly curat­ed images. The col­lec­tion itself is sub­di­vid­ed into dif­fer­ent pho­to albums drawn from his­tor­i­cal pub­li­ca­tions. For exam­ple, The Fresh­wa­ter Fish­es of the British Isles (1911), The Bird (1869), and The Insect Book (1901).

This image archive offers expan­sive views of human­i­ty’s encounter with the nat­ur­al world, not only through sta­tis­tics and aca­d­e­m­ic jar­gon, but through the artis­tic record­ing of won­der, sci­en­tif­ic curios­i­ty, and deep appre­ci­a­tion. Enter the archive here.

“The Matilda Effect”: How Pioneering Women Scientists Have Been Written Out of Science History

Pho­to via Wiki­me­dia Com­mons

The his­to­ry of sci­ence, like most every his­to­ry we learn, comes to us as a pro­ces­sion of great, almost exclu­sive­ly white, men, unbro­ken but for the occa­sion­al token woman—well-deserving of her hon­ors but seem­ing­ly anom­alous nonethe­less. “If you believe the his­to­ry books,” notes the Time­line series The Matil­da Effect, “sci­ence is a guy thing. Dis­cov­er­ies are made by men, which spur fur­ther inno­va­tion by men, fol­lowed by acclaim and prizes for men. But too often, there is an unsung woman genius who deserves just as much cred­it” and who has been over­shad­owed by male col­leagues who grabbed the glo­ry.

In 1993, Cor­nell Uni­ver­si­ty his­to­ri­an of sci­ence Mar­garet Rossiter dubbed the denial of recog­ni­tion to women sci­en­tists “the Matil­da effect,” for suf­frag­ist and abo­li­tion­ist Matil­da Joslyn Gage, whose 1893 essay “Woman as an Inven­tor” protest­ed the com­mon asser­tion that “woman… pos­sess­es no inven­tive or mechan­i­cal genius.” Such asser­tions, Gage pro­ceed­ed to demon­strate, “are care­less­ly or igno­rant­ly made… although woman’s sci­en­tif­ic edu­ca­tion has been gross­ly neglect­ed, yet some of the most impor­tant inven­tions of the world are due to her.”

Over 100 years lat­er, Rossiter’s tena­cious work in unearthing the con­tri­bu­tions of U.S. women sci­en­tists inspired the His­to­ry of Sci­ence Soci­ety to name a pres­ti­gious prize after her. The Time­line series pro­files a few of the women whom it describes as prime exam­ples of the Matil­da effect, includ­ing Dr. Lise Meit­ner, the Aus­tri­an-born physi­cist and pio­neer of nuclear tech­nol­o­gy who escaped the Nazis and became known in her time as “the Jew­ish Moth­er of the Bomb,” though she had noth­ing to do with the atom­ic bomb. Instead, “Meit­ner led the research that ulti­mate­ly dis­cov­ered nuclear fis­sion.” But Meit­ner would become “lit­tle more than a foot­note in the his­to­ry of Nazi sci­en­tists and the birth of the Atom­ic age.”

Instead, Meitner’s col­league Otto Hahn received the acco­lades, a Nobel Prize in Chem­istry and “renown as the dis­cov­er­er of nuclear fis­sion. Meit­ner, who direct­ed Hahn’s most sig­nif­i­cant exper­i­ments and cal­cu­lat­ed the ener­gy release result­ing from fis­sion, received a few essen­tial­ist head­lines fol­lowed by decades of obscu­ri­ty.” (See Meit­ner and Hahn in the pho­to above.) Like­wise, the name of Alice Augus­ta Ball has been “all but scrubbed from the his­to­ry of med­i­cine,” though it was Ball, an African Amer­i­can chemist from Seat­tle, Wash­ing­ton, who pio­neered what became known as the Dean Method, a rev­o­lu­tion­ary treat­ment for lep­rosy.

Ball con­duct­ed her research at the Uni­ver­si­ty of Hawaii, but she trag­i­cal­ly died at the age of 24, in what was like­ly a lab acci­dent, before the results could be pub­lished. Instead, Uni­ver­si­ty Pres­i­dent Dr. Arthur Dean, who had co-taught chem­istry class­es with Ball, con­tin­ued her work. But he failed “to men­tion Ball’s key con­tri­bu­tion” despite protes­ta­tions from Dr. Har­ry Holl­mann, a sur­geon who worked with Ball on treat­ing lep­rosy patients. Dean claimed cred­it and pub­lished their work under his name. Decades lat­er, “the scant archival trail of Alice Ball was redis­cov­ered…. In 2000, a plaque was installed at the Uni­ver­si­ty of Hawaii com­mem­o­rat­ing Ball’s accom­plish­ments.”

Oth­er women in the Matil­da effect series include bac­te­r­i­al geneti­cist Esther Leder­berg, who made amaz­ing dis­cov­er­ies in genet­ics that won her hus­band a Nobel Prize; Irish astro­physi­cist Joce­lyn Bell Bur­nell, who dis­cov­ered the first radio pul­sars in 1967, but was exclud­ed from the Nobel award­ed to her the­sis super­vi­sor Antony Hewish and astronomer Mar­tin Ryle. A sim­i­lar fate befell Dr. Ros­alind Franklin, the chemist exclud­ed from the Nobel award­ed to her col­leagues James Wat­son, Fran­cis Crick, and Mau­rice Wilkins for the dis­cov­ery of DNA.

These promi­nent exam­ples are but the tip of the ice­berg when it comes to women who made sig­nif­i­cant con­tri­bu­tions to sci­en­tif­ic his­to­ry and were reward­ed by being writ­ten out of it and denied awards and recog­ni­tion in their life­time. For more on the his­to­ry of U.S. women in sci­ence and the social forces that worked to exclude them, see Mar­garet Rossiter’s three-vol­ume Women Sci­en­tists in Amer­i­ca series: Strug­gles and Strate­gies to 1940, Before Affir­ma­tive Action, 1940–1972, and Forg­ing a New World since 1972.

Nikola Tesla Accurately Predicted the Rise of Wireless Technology & the Smartphone in 1926

Cer­tain cult his­tor­i­cal fig­ures have served as pre­scient avatars for the tech­no-vision­ar­ies of the dig­i­tal age. Where the altru­is­tic utopi­an designs of Buck­min­ster Fuller pro­vid­ed an ide­al for the first wave of Sil­i­con Val­ley pio­neers (a group includ­ing com­put­er sci­en­tist and philoso­pher Jaron Lanier and Wired edi­tor Kevin Kel­ly), lat­er entre­pre­neurs have hewn clos­er to the prin­ci­ples of bril­liant sci­en­tist and inven­tor Niko­la Tes­la, who believed, as he told Lib­er­ty mag­a­zine in 1935, that “we suf­fer the derange­ment of our civ­i­liza­tion because we have not yet com­plete­ly adjust­ed our­selves to the machine age.”

Such an adjust­ment would come, Tes­la believed, only in “mas­ter­ing the machine”—and he seemed to have supreme con­fi­dence in human mastery—over food pro­duc­tion, cli­mate, and genet­ics. We would be freed from oner­ous labor by automa­tion and the cre­ation of “a think­ing machine,” he said, over a decade before the inven­tion of the com­put­er. Tes­la did not antic­i­pate the ways such machines would come to mas­ter us, even though he can­ni­ly fore­saw the future of wire­less tech­nol­o­gy, com­put­ing, and tele­pho­ny, tech­nolo­gies that would rad­i­cal­ly reshape every aspect of human life.

In an ear­li­er, 1926, inter­view in Col­lier’s mag­a­zine, Tes­la pre­dict­ed, as the edi­tors wrote, com­mu­ni­cat­ing “instant­ly by sim­ple vest-pock­et equip­ment.” His actu­al words con­veyed a much grander, and more accu­rate, pic­ture of the future.

When wire­less is per­fect­ly applied the whole earth will be con­vert­ed into a huge brain, which in fact it is…. We shall be able to com­mu­ni­cate with one anoth­er instant­ly, irre­spec­tive of dis­tance. Not only this, but through tele­vi­sion and tele­pho­ny we shall see and hear one anoth­er as per­fect­ly as though we were face to face, despite inter­ven­ing dis­tances of thou­sands of miles; and the instru­ments through which we shall be able to do this will be amaz­ing­ly sim­ple com­pared with our present tele­phone. A man will be able to car­ry one in his vest pock­et. 

The com­plex­i­ty of smart­phones far out­strips that of the tele­phone, but in every oth­er respect, Tesla’s pic­ture maps onto the real­i­ty of almost 100 years lat­er. Oth­er aspects of Tesla’s future sce­nario for wire­less also seem to antic­i­pate cur­rent tech­nolo­gies, like 3D print­ing, though the kind he describes still remains in the realm of sci­ence fic­tion: “Wire­less will achieve the clos­er con­tact through trans­mis­sion of intel­li­gence, trans­port of our bod­ies and mate­ri­als and con­veyance of ener­gy.”

But Tesla’s vision had its lim­i­ta­tions, and they lay pre­cise­ly in his tech­no-opti­mism. He nev­er met a prob­lem that wouldn’t even­tu­al­ly have a tech­no­log­i­cal solu­tion (and like many oth­er tech­no-vision­ar­ies of the time, he hearti­ly endorsed state-spon­sored eugen­ics). “The major­i­ty of the ills from which human­i­ty suf­fers,” he said, “are due to the immense extent of the ter­res­tri­al globe and the inabil­i­ty of indi­vid­u­als and nations to come into close con­tact.”

Wire­less tech­nol­o­gy, thought Tes­la, would help erad­i­cate war, pover­ty, dis­ease, pol­lu­tion, and gen­er­al dis­con­tent, when we are “able to wit­ness and hear events—the inau­gu­ra­tion of a Pres­i­dent, the play­ing of a world series game, the hav­oc of an earth­quake or the ter­ror of a battle—just as though we were present.” When inter­na­tion­al bound­aries are “large­ly oblit­er­at­ed” by instant com­mu­ni­ca­tion, he believed, “a great step will be made toward the uni­fi­ca­tion and har­mo­nious exis­tence of the var­i­ous races inhab­it­ing the globe.”

Tes­la did not, and per­haps could not, fore­see the ways in which tech­nolo­gies that bring us clos­er togeth­er than ever also, and at the same time, pull us ever fur­ther apart. Read Tes­la’s full inter­view here, in which he also pre­dicts that women will become the “supe­ri­or sex,” not by virtue of “the shal­low phys­i­cal imi­ta­tion of men” but through “the awak­en­ing of the intel­lect.”

Einstein’s Divorce Letters and the Cruel List of Marital Demands He Imposed on His First Wife

Albert Ein­stein is the rare fig­ure who’s uni­ver­sal­ly known, but almost entire­ly for his pro­fes­sion­al achieve­ments. Few of us who can explain the the­o­ry of rel­a­tiv­i­ty can also say much about the per­son­al life of the man who came up with it, though that does­n’t owe to a lack of doc­u­men­ta­tion. Thanks to sci­ence YouTu­ber Toby Hendy, we have, for exam­ple, some of the love let­ters he wrote to the women who con­sti­tut­ed a ver­i­ta­ble parade through his life. Also, in anoth­er video for her chan­nel Tibees, Hendy reads the let­ters he wrote in the process of divorc­ing his first wife, the Ser­bian physi­cist and math­e­mati­cian Mil­e­va Mar­ić.

Ein­stein mar­ried Mar­ić in Jan­u­ary 1903, says Hendy, “after they had been togeth­er for around five years. The rela­tion­ship was in its prime, and so was the aca­d­e­m­ic pro­duc­tiv­i­ty. It was in 1905 that Ein­stein would pub­lish his four major papers that would change the face of physics. By 1912, how­ev­er, Ein­stein had start­ed hav­ing an affair with his cousin,” Elsa Lowen­thal.

By 1914, Ein­stein wrote to Mar­ić a let­ter “detail­ing some con­di­tions of them con­tin­u­ing to live togeth­er,” if not quite as man and wife. The con­di­tions read as fol­lows:

CONDITIONS

A. You will make sure:

1. that my clothes and laun­dry are kept in good order;
2. that I will receive my three meals reg­u­lar­ly in my room;
3. that my bed­room and study are kept neat, and espe­cial­ly that my desk is left for my use only.

B. You will renounce all per­son­al rela­tions with me inso­far as they are not com­plete­ly nec­es­sary for social rea­sons. Specif­i­cal­ly, You will forego:

1. my sit­ting at home with you;
2. my going out or trav­el­ling with you.

C. You will obey the fol­low­ing points in your rela­tions with me:

1. you will not expect any inti­ma­cy from me, nor will you reproach me in any way;
2. you will stop talk­ing to me if I request it;
3. you will leave my bed­room or study imme­di­ate­ly with­out protest if I request it.

D. You will under­take not to belit­tle me in front of our chil­dren, either through words or behav­ior.

Though they agreed to put this strin­gent plan into effect, less than two weeks lat­er, he wrote to Elsa, “Yes­ter­day my wife left for good with the chil­dren” — and “you, dear lit­tle Elsie, will now become my wife and become con­vinced that it is not at all so hard to live by my side.”

Ein­stein did mar­ry Lowen­thal in 1919, and the union, though hard­ly char­ac­ter­ized by ide­al faith­ful­ness, did last until her death in 1935. There would be plen­ty of oth­er women, but none who played quite the same role in his life as Mar­ić, not only the moth­er of his chil­dren, but also — accord­ing to some his­to­ri­ans — a col­lab­o­ra­tor on some of his accom­plish­ments in physics. Accord­ing to Lost Women of Sci­ence, “there is lit­tle tan­gi­ble evi­dence to sup­port the claims that Mar­ić was a co-author of Einstein’s first major work. That said, there are plen­ty of per­son­al tes­ti­monies from those who knew Mar­ić and Ein­stein that her involve­ment was like­ly.” One con­di­tion of their divorce set­tle­ment, at any rate, held that Mar­ić receive his Nobel Prize mon­ey, were he to win it, which he went on to do a cou­ple of years lat­er. This makes clear that, what­ev­er the impor­tance of her own sci­en­tif­ic work, she must’ve had a good head on her shoul­ders.

Remembering Jane Goodall (RIP): Watch Jane, the Acclaimed National Geographic Documentary

Jane Goodall, the revered con­ser­va­tion­ist, passed away today at age 91. In her hon­or, we’re fea­tur­ing above a Nation­al Geo­graph­ic doc­u­men­tary called Jane. Direct­ed by Brett Mor­gen, the film draws “from over 100 hours of nev­er-before-seen footage that has been tucked away in the Nation­al Geo­graph­ic archives for over 50 years.” The doc­u­men­tary offers an inti­mate por­trait of Goodall and her chim­panzee research that “chal­lenged the male-dom­i­nat­ed sci­en­tif­ic con­sen­sus of her time and rev­o­lu­tion­ized our under­stand­ing of the nat­ur­al world.” It’s set to an orches­tral score by com­pos­er Philip Glass.

Carl Sagan’s Baloney Detection Kit: Tools for Thinking Critically & Knowing Pseudoscience When You See It

Though he died too young, Carl Sagan left behind an impres­sive­ly large body of work, includ­ing more than 600 sci­en­tif­ic papers and more than 20 books. Of those books, none is more wide­ly known to the pub­lic — or, still, more wide­ly read by the pub­lic — than Cos­mos, accom­pa­nied as it was by Cos­mos: A Per­son­al Voy­age, a com­pan­ion tele­vi­sion series on PBS. Sagan’s oth­er pop­u­lar books, like Shad­ows of For­got­ten Ances­tors or Con­tact (the basis of the 1997 Hol­ly­wood movie) are also well worth read­ing, but we per­haps ignore at our great­est per­il The Demon-Haunt­ed World: Sci­ence as a Can­dle in the Dark. Pub­lished in 1995, the year before Sagan’s death, it stands as his tes­ta­ment to the impor­tance of crit­i­cal, sci­en­tif­ic think­ing for all of us.

The Demon-Haunt­ed World is the sub­ject of the Genet­i­cal­ly Mod­i­fied Skep­tic video above, whose host Drew McCoy describes it as his favorite book. He pays spe­cial atten­tion to its chap­ter in which Sagan lays out what he calls his “baloney detec­tion kit.” This assem­bled metaphor­i­cal box of tools for diag­nos­ing fraud­u­lent argu­ments and con­struct­ing rea­soned ones involves these nine prin­ci­ples:

  • Wher­ev­er pos­si­ble there must be inde­pen­dent con­fir­ma­tion of the “facts.”
  • Encour­age sub­stan­tive debate on the evi­dence by knowl­edge­able pro­po­nents of all points of view.
  • Argu­ments from author­i­ty car­ry lit­tle weight — “author­i­ties” have made mis­takes in the past. They will do so again in the future. Per­haps a bet­ter way to say it is that in sci­ence there are no author­i­ties; at most, there are experts.
  • Spin more than one hypoth­e­sis. If there’s some­thing to be explained, think of all the dif­fer­ent ways in which it could be explained. Then think of tests by which you might sys­tem­at­i­cal­ly dis­prove each of the alter­na­tives.
  • Try not to get over­ly attached to a hypoth­e­sis just because it’s yours. It’s only a way sta­tion in the pur­suit of knowl­edge. Ask your­self why you like the idea. Com­pare it fair­ly with the alter­na­tives.
  • See if you can find rea­sons for reject­ing it. If you don’t, oth­ers will.
  • If what­ev­er it is you’re explain­ing has some mea­sure, some numer­i­cal quan­ti­ty attached to it, you’ll be much bet­ter able to dis­crim­i­nate among com­pet­ing hypothe­ses. What is vague and qual­i­ta­tive is open to many expla­na­tions.
  • If there’s a chain of argu­ment, every link in the chain must work (includ­ing the premise) — not just most of them.
  • Occam’s Razor. This con­ve­nient rule-of-thumb urges us when faced with two hypothe­ses that explain the data equal­ly well to choose the sim­pler. Always ask whether the hypoth­e­sis can be, at least in prin­ci­ple, fal­si­fied…. You must be able to check asser­tions out. Invet­er­ate skep­tics must be giv­en the chance to fol­low your rea­son­ing, to dupli­cate your exper­i­ments and see if they get the same result.

As McCoy points out, these tech­niques of mind have to do with can­cel­ing out the man­i­fold bias­es present in our think­ing, those nat­ur­al human ten­den­cies that incline us to accept ideas that may or may not coin­cide with real­i­ty as it is. If we take no trou­ble to cor­rect for these bias­es, Sagan came to believe, we’ll become easy marks for all the trick­sters and char­la­tans who hap­pen to come our way. And that’s just on the micro lev­el: on the macro lev­el, vul­ner­a­bil­i­ty to delu­sion can bring down entire civ­i­liza­tions.

“Like all tools, the baloney detec­tion kit can be mis­used, applied out of con­text, or even employed as a rote alter­na­tive to think­ing,” Sagan cau­tions. “But applied judi­cious­ly, it can make all the dif­fer­ence in the world — not least in eval­u­at­ing our own argu­ments before we present them to oth­ers.” McCoy urges us to heed these words, adding that “this kit is not some per­fect solu­tion to the world’s prob­lems, but as it’s been uti­lized over the last few cen­turies” — for its basic pre­cepts long pre­date Sagan’s par­tic­u­lar artic­u­la­tion — “it has enabled us to cre­ate tech­no­log­i­cal inno­va­tions and use­ful explana­to­ry mod­els of our world more quick­ly and effec­tive­ly than ever before.” The walls of baloney may always be clos­ing in on human­i­ty, but if you fol­low Sagan’s advice, you can at least give your­self some breath­ing room.
