Subskill: Avoid pitfalls of verbal strategic reasoning.

• List consequences without shifting from intuitive-sum to verbal-justification mode.
• Don't exacerbate scope insensitivity or attending to rare events.

There are studies showing that people who consider their decisions more make worse decisions. As I understand it, the main explanation for this is that people shift from an intuitive sum of costs and benefits, to seeking verbally justifiable decisions, which in turn might lead them to one-reason-decisionmaking, ignoring some of their costs and benefits which are important to them but seem less "sensible". I also suspect it may exacerbate other biases like scope insensitivity or rare events - thinking about cases which are rare or short in duration.

The classic case being "Let's get a bigger house, further away from work, so it has an extra bedroom in case Grandma comes over", which she does once a year, but the 20 minutes of extra commute time happen every day and are not acclimated-to.
