Mental Models That Make Every Decision Sharper
Second-order thinking, inversion, and first principles expose what you're missing. The right mental model turns a hard decision into an obvious one.
What was corrected
The article cited a Berk-van Binsbergen 2016 JFE 10-15% skill finding, a Fresard 2019 consistent-framework result, an Ericsson-Whyte-Ward 2007 diagnostic-accuracy study, a fixed 5-10x engineering safety factor, and practitioner cases proving mental models caused performance.
Fixed the Berk-van Binsbergen citation and finding, generalized the unverifiable Fresard and Ericsson results, corrected the safety-factor figure, and framed practitioner cases as illustrations.
Why this is better
Several citations named the wrong year/journal or a study that could not be verified, and the safety-factor figure was wrong. Corrections fix the citations and figures and scope the claims rather than adding new sources.
