First conclusions become nearly permanent — the brain resists its own updates
Inconsistency-Avoidance Tendency means early-formed habits and first conclusions are maintained even against strong disconfirming evidence
Systems that prevent bad behavior beat moral appeals — design the cash register, not the sermon
People who create mechanisms making dishonest behavior hard to accomplish are more effective than those who preach against dishonesty
Excessive self-regard makes fixable failures persist — people excuse poor performance instead of correcting it
The Tolstoy effect causes people to rationalize fixable shortcomings rather than address them, requiring meritocratic culture and objective evaluation as antidotes
Incentive-caused bias makes good people rationalize harmful behavior
People don't consciously choose to be unethical — incentive structures cause them to drift into immoral behavior and then rationalize it as virtuous
Confluence of tendencies produces extreme outcomes — lollapalooza effects emerge when multiple psychological biases push the same direction
When several psychological tendencies combine toward the same outcome, the result is not additive but explosive — Munger's checklist method diagnoses these compound failures
Pavlovian association builds durable brand moats that compound for over a century
Brands are conditioned reflexes — the trade name is the stimulus, purchase is the response, and Pavlovian association with things consumers admire creates advantages that scale economics alone cannot explain
Social proof makes groups passive before visible harm — conformity overrides individual judgment even in life-or-death situations
Social-Proof Tendency causes individuals to follow the crowd into inaction or corruption, with bystander apathy and institutional silence as its most dangerous manifestations

Every person has a circle of competence — playing inside it with discipline compounds advantage, playing outside it guarantees loss, and it's very hard to enlarge

Non-attached action enables clearer course correction — detach from outcomes to see reality
Acting without attachment to being right, to a specific outcome, or to whose idea it was lets you see when something isn't working and change course without ego friction
Small concessions trigger disproportionate reciprocation — even at the subconscious level
Reciprocation Tendency operates below conscious awareness, making tiny favors or concessions produce outsized compliance — the only reliable defense is structural prohibition
