Heuris­tics & Biases

TagLast edit: 2 Oct 2020 18:36 UTC by Ruby

Heuris­tics and Bi­ases are the ways hu­man rea­son­ing differs from a the­o­ret­i­cal ideal agent, due to rea­son­ing short­cuts that don’t always work (heuris­tics) and sys­tem­atic er­rors (bi­ases).

“Cog­ni­tive bi­ases” are those ob­sta­cles to truth which are pro­duced, not by the cost of in­for­ma­tion, nor by limited com­put­ing power, but by the shape of our own men­tal ma­chin­ery. For ex­am­ple, our men­tal pro­cesses might be evolu­tion­ar­ily adapted to speci­fi­cally be­lieve some things that ar­ent true, so that we could win poli­ti­cal ar­gu­ments in a tribal con­text. Or the men­tal ma­chin­ery might be adapted not to par­tic­u­larly care whether some­thing is true, such as when we feel the urge to be­lieve what oth­ers be­lieve to get along so­cially. Or the bias may be a side-effect of a use­ful rea­son­ing heuris­tic. The availa­bil­ity heuris­tic is not it­self a bias, but it gives rise to them; the ma­chin­ery uses an al­gorithm (give things more ev­i­den­tial weight if they come to mind more read­ily) that does some good cog­ni­tive work but also pro­duces sys­tem­atic er­rors.

Our brains are do­ing some­thing wrong, and af­ter a lot of ex­per­i­men­ta­tion and/​or heavy think­ing, some­one iden­ti­fies the prob­lem ver­bally and con­cretely; then we call it a “(cog­ni­tive) bias.” Not to be con­fused with the col­lo­quial “that per­son is bi­ased,” which just means “that per­son has a skewed or prej­u­diced at­ti­tude to­ward some­thing.”

A bias is an ob­sta­cle to our goal of ob­tain­ing truth, and thus in our way.

We are here to pur­sue the great hu­man quest for truth: for we have des­per­ate need of the knowl­edge, and be­sides, we’re cu­ri­ous. To this end let us strive to over­come what­ever ob­sta­cles lie in our way, whether we call them “bi­ases” or not.

It’s also use­ful to know the kinds of faults hu­man brains are prone to, in the same way it’s use­ful to know that your car’s brakes are a lit­tle gummy (so you don’t sail through a red light and into an 18-wheeler).

The Se­quence, Pre­dictably Wrong, offers an ex­cel­lent in­tro­duc­tion to the topic for those who are not fa­mil­iar.

Wait a minute… fal­la­cies, bi­ases, heuris­tics… what’s the differ­ence??

While a bias is always wrong, a heuris­tic is just a short­cut which may or may not give you an ac­cu­rate an­swer. Just be­cause you know com­plex math­e­mat­i­cal meth­ods for pre­cisely calcu­lat­ing the flight of ob­jects through space doesn’t mean you should be us­ing them to play vol­ley­ball. Which is to say, heuris­tics are nec­es­sary for ac­tu­ally get­ting any­thing done. But be­cause they are just ap­prox­i­ma­tions they fre­quently pro­duce bi­ases, which is where the prob­lem lies. “Fal­lacy” is of­ten used to mean a very similar thing as bias on LessWrong. [Needs bet­ter clar­ifi­ca­tion]

A good ex­am­ple of a heuris­tic is the af­fect heuris­tic—peo­ple tend to guess un­known traits about peo­ple or things based on the per­ceived good­ness of bad­ness of known traits. In some cir­cum­stances this is a use­ful short­cut—you may like to as­sume, for in­stance, that peo­ple who are good singers are more likely to be good dancers, too. How­ever, it also fre­quently pro­duces (un­con­scious) bi­ases—a bias to­wards be­liev­ing that peo­ple who are tall and good look­ing have bet­ter moral char­ac­ter, for in­stance.

So if I learn all the bi­ases, I can con­quer the world with my su­pe­rior in­tel­lect?

Well, no. If it were that easy we wouldn’t need a com­mu­nity ini­tially ded­i­cated to over­com­ing bias (the name of the blog which this web­site grew out of). Un­for­tu­nately, learn­ing about a bias alone doesn’t seem to im­prove your abil­ity to avoid it in real life. There’s also the (ma­jor) is­sue that know­ing about bi­ases can hurt peo­ple. In­stead of be­ing purely fo­cused on re­mov­ing nega­tive habits, there is now a ma­jor fo­cus at LessWrong to im­ple­ment­ing pos­i­tive habits. Th­ese are skills such as how to up­date (change your mind) the cor­rect amount in re­sponse to ev­i­dence, how to re­solve dis­agree­ments with oth­ers, how to in­tro­spect, and many more.

...What’s a bias, again?
