5 Mental Models to Remove (Some of) the Confusion from Parenting
Farnam Street (Shane Parrish) · 2022
"Rather than adopting rigid parenting tactics that may not fit your specific child, five underlying principles — adaptation, velocity, algebraic equivalence, seizing the middle, and inversion — generalize across any family, situation, or child, because they're principles rather than one-size-fits-all scripts."
The five models are: adaptation (parenting rules can differ by context — home vs. public, child vs. child — without being 'inconsistent,' just as species adapt differently to different environments); velocity (are you spending time with direction toward a goal, or just moving fast without purpose); algebraic equivalence (two things can be different yet equal, e.g., different amounts of attention to different children can still represent equal love, the way x+y=5 has many valid solutions); seizing the middle (like chess, control the central territory — mutual trust and respect — rather than fighting every minor battle); and inversion (sometimes progress comes from removing an obstacle, not adding a new tactic).
The mechanism that makes these five 'generalize' where specific tactics don't is that they're principles about how to think, not prescribed behaviors — a rule like 'always let children cry it out' either fits a specific child and situation or it doesn't, but a principle like 'seize the middle territory of trust, not every minor battle' can be applied freshly to whatever specific conflict arises, adapting the tactic to the child rather than forcing the child to fit a fixed tactic.
What does 'algebraic equivalence,' as used in this parenting piece, help explain?

Mental Models for Career Changes
"A career change is best approached with a stack of specific mental models — velocity (direction, not just motion), inversion (working backward from the desired end-state), exaptation (repurposing existing skills for new uses), map-vs-territory (getting real information, not just impressions), and the 'Bayesian casino' (quantifying your actual confidence with a hypothetical bet) — rather than by pure gut feeling."
