Already cov­ered to death, it’s been on my book­marks list since I read the fol­low­ing from Wired edi­tor Mark Horowitz on it’s day of publication:

Best/worst day. Story I am proud­est of assign­ing and edit­ing at Wired goes live today. […] But I also lose job. Bummer!

That story is a fan­tas­ti­cally well writ­ten and researched arti­cle look­ing at the snake oil ped­dled by the anti-vaccine crowd and why peo­ple lis­ten to, and fall for, their pseudo-science (i.e. per­ceived risk and irrationality).

The rejec­tion of hard-won knowl­edge is by no means a new phe­nom­e­non. In 1905, French math­e­mati­cian and sci­en­tist Henri Poin­caré said that the will­ing­ness to embrace pseudo-science flour­ished because peo­ple “know how cruel the truth often is, and we won­der whether illu­sion is not more con­sol­ing.” Decades later, the astronomer Carl Sagan reached a sim­i­lar con­clu­sion: Sci­ence loses ground to pseudo-science because the lat­ter seems to offer more com­fort. “A great many of these belief sys­tems address real human needs that are not being met by our soci­ety,” Sagan wrote of cer­tain Amer­i­cans’ embrace of rein­car­na­tion, chan­nel­ing, and extrater­res­tri­als. “There are unsat­is­fied med­ical needs, spir­i­tual needs, and needs for com­mu­nion with the rest of the human community.”

Look­ing back over human his­tory, ratio­nal­ity has been the anom­aly. Being ratio­nal takes work, edu­ca­tion, and a sober deter­mi­na­tion to avoid mak­ing hasty infer­ences, even when they appear to make per­fect sense. Much like infec­tious dis­eases them­selves — beaten back by decades of effort to vac­ci­nate the pop­u­lace — the irra­tional lingers just below the sur­face, wait­ing for us to let down our guard.

I post this now as in recent days Andrew Wake­field—the physi­cian who linked the three-in-one MMR vac­cine to autism—has had his orig­i­nal arti­cle fully retracted by the med­ical jour­nal The Lancet after the Gen­eral Med­ical Coun­cil found he acted “dis­hon­estly and irre­spon­si­bly” with “cal­lous dis­re­gard” and had a con­flict of inter­est in his study.
