Confirmation Bias Isn’t a Bug, It’s Operator Error
A key cognitive bias isn’t a bug, it’s just operator error (and easily correctable by using reason as nature intended).
1. Science has good news on minds, for a change. A key cognitive bias isn’t a bug, it’s just operator error (and easily correctable by using reason as nature intended).
2. In The Enigma of Reason, Hugo Mercier and Dan Sperber (M&S), articulate an “argumentative theory of reasoning.” Their “interactionist” views contrast sharply from the prevailing individualist “intellectualism.”
4. An analogy between reason and sight can enlighten here. Eyesight isn’t a direct window onto reality. It detects limited wavelengths, needs many interpretative steps between received light and sight, and suffers optical illusions (that are tellingly not survival-threatening).
6. Our brains are built and “biased” to enable evolutionarily useful behaviors. And solving abstract logic problems is an evolutionary novelty (e.g., only possible after the invention of the technology of writing). So reason evolved mainly “to resolve the problems posed by living in collaborative groups.”
8. But, they emphasize, there’s no evolutionary sense in being predisposed to pigheadedly sticking to your beliefs. You’re often better off changing your mind and using better ideas from trusted others (cognitive division of labor). So we evolved to be persuadable (by sufficiently good, trustworthy, reasons), as M&S describe in chapter 15 “The Bright Side of Reason.”
9. M&S’s argumentative theory is often misrepresented as reason being like your inner lawyer’s win-at-all-costs “weapon.” But good lawyers know when to concede to stronger arguments. They negotiate in their clients’ better interests.
11. Not thinking too hard about your first justification and relying on the “epistemic vigilance” of co-reasoners is often a good division of “cognitive labor,” that efficiently generates better decisions (= clearly adaptive, if you can avoid being manipulated or misinformed).
13. There’s much more in The Enigma of Reason (e.g., intuition’s role in all reasoning, or countering “dual systems” views, see Kahneman). And more work is needed (e.g. on trust, power, and intuition-shifting processes) but M&S’s work—perhaps better called the “negotiative theory of reasoning” or “social theory of reasoning”— represents progress.
14. Individualist Enlightenment thinkers mostly haven’t enlightened us about our inalienably social minds. Rather, the “Age of Reason” has tended to promote unempirical, unevolutionary, over-rationalist, over-individualist thinking (=delusions).
15. Clearer thinkers aren’t blinkered by the aspirational projections of solitary geniuses. They see how extensive cognitive division of labor, and reliance on the minds of others, means we exceed the capabilities of our individual minds.

Philosophers like to present their works as if everything before it was wrong. Sometimes, they even say they have ended the need for more philosophy. So, what happens when somebody realizes they were mistaken?
Sometimes philosophers are wrong and admitting that you could be wrong is a big part of being a real philosopher. While most philosophers make minor adjustments to their arguments to correct for mistakes, others make large shifts in their thinking. Here, we have four philosophers who went back on what they said earlier in often radical ways.
We must rethink the "chemical imbalance" theory of mental health.
- A new review found that withdrawal symptoms from antidepressants and antipsychotics can last for over a year.
- Side effects from SSRIs, SNRIs, and antipsychotics last longer than benzodiazepines like Valium or Prozac.
- The global antidepressant market is expected to reach $28.6 billion this year.
