Statements from this episode (38)
Charlie Munger: People Consistently Underestimate the Power of Incentives
“Well, I think I've been in the top five percent of my age cohort all my life in understanding the power of incentives, and all my life I've underestimated it. And Never a year passes, but what I get some surprise that pushes my limit a little farther.”
Parrish: FedEx Solved Overnight Delays by Paying Shifts Instead of Hourly
“Pay them by the shift, so when they're done, they can just go home. The problem ended literally overnight.”
Parrish: Loving admirable people and ideas creates a major life advantage
“Munger points out that loving admirable people and ideas with special intensity is a huge advantage in life. Liking the right people and the right behaviors helps you become a better person.”
Parrish: Test investment bias by asking if you'd buy today at market price
“And in investing, ask yourself, if I didn't already own this, would I buy it today at the current price? If the answer was no, you might be driven by liking tendency and not rational analysis.”
Parrish: Hatred of Opponents Motivates People More Easily Than Love of Candidates
“It's easier to motivate people through hatred of an opponent than through love of your own candidate.”
Parrish: Inability to Find Any Virtue in Disliked Entities Proves Cognitive Bias
“The antidote here is to force yourself to see the virtues, even in what you dislike. Ask yourself, what is this person, company, idea doing well? If you genuinely can't think of a single thing, that's the hating tendency at work.”
Parrish: Delaying Intuition Across Separate Dimensions Produces Better Decisions
“When I talked to Daniel Kahneman about this, he said, you delay intuition by focusing on the separate problems. Take the separate dimensions and really think about each dimension separately and independently. Don't allow people to give the final judgment. Say,…”
Parrish: Older Einstein Rejected Quantum Mechanics Due to Inconsistency Avoidance
“Early Einstein was brilliant at destroying his own previous ideas, But the older Einstein never accepted the full implications of quantum mechanics, partly because it was inconsistent with conclusions he'd reached at his peak.”
Parrish: Overcome Sunk Cost by Asking How to Decide Fresh Today
“Ask yourself, if I were making this decision fresh today with no history, what would I do? If the answer is different, act on it.”
Parrish: Disproportionate anger often stems from violated fairness expectations
“When someone responds with disproportionate anger about something small, often it's because their sense of fairness was violated.”
Parrish: Law firms flatten partner pay to avoid destructive envy
“Many big law firms fearing disorder from envy and jealousy have long treated all senior partners alike In compensation, no matter how different their contributions to firm welfare, they're willing to destroy their incentive structure just to avoid triggering e…”
Parrish: Emotional detachment from envy provides investors a massive advantage
“Munger and Buffett's advantage was that they genuinely didn't seem to experience envy. When asked about missing opportunities, they'd shrug and move on. When competitors succeeded, they'd analyze what happened objectively. This emotional detachment is a massiv…”
Parrish: Political and social conflict is often fueled by envy, not principles
“Third, understand that much political and social conflict that appears to be about principles is actually driven by envy. The principles might be real, but the anger comes from envy.”
Parrish: Preceding requests with extreme demands triples compliance to 50%
“First, researchers asked people to supervise delinquents for two years. This got a 100% rejection. But then he asked, will you at least spend one afternoon taking them to the zoo? And the acceptance rate tripled to 50%.”
Parrish: Sam Walton banned Walmart buyers from accepting vendor gifts
“At Walmart, he wouldn't let purchasing agents accept so much as a hot dog from vendors.”
Parrish: Raising Prices on Ordinary Products Frequently Drives Up Sales
“Knowing this, some seller of an ordinary industrial product will often change his product's trade dress and raise its price significantly, hoping the quality-seeking buyers will be tricked into becoming purchasers by mere association of his product and its hig…”
Parrish: Berkshire Hathaway Enforces Rule Requiring Prompt Delivery of Bad News
“At Berkshire Hathaway, there's a common injunction. Always tell us the bad news promptly. It is only the good news that can wait. This is a deliberate practice to combat the Persian messenger syndrome.”
Munger: Family Friend Exhibited Extreme Denial Over Lost Naval Aviator Son
“This first really hit me between the eyes when a friend of our family had a Super athlete, super student son who flew off a carrier in the North Atlantic and never came back. And his mother, who had, was a very sane woman, just never believed that he was dead.”
Parrish: Psychological Denial Eliminates Clear-Eyed Assessment Before It Is Recognized
“Don't rely on your ability to see clearly once denial has set in. By the time denial activates, you've already lost the ability to accurately assess the situation.”
Parrish: Employers Overrate In-Person Interviews Instead of Past Track Records
“Employers grossly over-appraised the worth of face-to-face impressions. The anecdote to this is to underweight face-to-face impressions and overweight the applicant's Past track record.”
Munger: Evolved risk heuristics fail like an untaught golf grip
“The mental rules of thumb that evolution gives us to deal with risk are not adequate, Munger writes. They resemble the dysfunctional golf grip you would have if you relied on evolution instead of golf lessons.”
Parrish: Near-misses trigger the same psychological pain as losing long-held possessions
“This is the pain of losing something is much higher than the pleasure of gaining the same thing. Losing 10 dollars hurts more than gaining 10 dollars feels good, and if you almost get something you want and it's jerked away from you at the last moment, you rea…”
Parrish: Open outcry auctions exploit social proof and deprival bias to drive overbidding
“Open outcry auctions are designed to trigger this too. You bid, and then someone outbids you. You almost had it. Just one more bid. The cycle keeps going. Social proof convinces you the last price was reasonable, and deprival super reaction makes you desperate…”
Parrish: Warren Buffett avoids auctions entirely to dodge psychological bias
“Warren Buffett's solution to this was very practical. Don't go to auctions.”
Parrish: Social proof is most powerful under simultaneous confusion and stress
“Social proof triggers most powerfully when you're puzzled or stressed, when you're both At the same time, that's when you're most vulnerable.”
Munger: Oil companies copied fertilizer acquisitions without reason, ending in disaster
“Big shot businessmen get into these waves of social proof. Do you remember some years ago when one oil company bought a fertilizer company? And every other major oil company practically ran out and bought a fertilizer company. And there was no more damn reason…”
Parrish: Businesses fail from gradual deterioration that goes unnoticed
“Businesses die exactly the same way. Slow deterioration that nobody notices because each day is only slightly worse than the day before.”
Munger: Pavlov's flood-trapped dogs showed total reversal of conditioned personality
“Here my favorite example is, is, is the great Pavlov, and he had all these dogs in cages, which had all been conditioned into changed behaviors, and the great Leningrad flood came, and it just went right up, and the dog's in a cage, and the dog had as much str…”
Parrish: Pavlov found any dog breaks under stress with zero exceptions
“One, he could predict which dogs would break down easily, and which would be harder to break. Two, the dogs that were hardest to break were also the hardest to fix afterward. Three, any dog could be broken with enough stress. There were no exceptions. Four, he…”
Parrish: Maximal stress can flip loyalties and reverse prior beliefs
“First, extreme stress can completely flip your cognitive patterns and loyalties. People under maximal stress don't just think worse. They can end up thinking the complete opposite of what they believed before.”
Munger: Elderly people naturally disguise age-related deterioration through social conventions
“He said, old people like me get pretty skilled without working at it, at disguising age-related deterioration because social convention like clothing hides much decline.”
Parrish: Co-Pilots in Simulations Fail to Override Fatal Captain Errors
“Co-pilots get simulator training specifically teaching them to ignore foolish orders from boss pilots. From the captain. But even after this training, co-pilots in simulators will still allow the plane to crash because of some obvious error created by the chie…”
Parrish: Authority Misinfluence Protects Incompetent CEOs from Removal
“Munger's observation is that undue respect for authority is so strong that terrible CEOs remain in control of important institutions long after it's obvious they should be removed. Authority misinfluence tendency protects them.”
Munger: Organizations must isolate decision-making from people with say-something syndrome
“And it's a very important part of human organization to set things up so the noise and the reciprocation and so forth, of all these people who have what I call say-something syndrome, don't really affect the decisions.”
Parrish: Karl Braun fired employees who omitted 'why' from memos
“He had a simple rule in his company. You had to tell who was to do what, where, when, and why. If you wrote a memo or gave an order and left out the why, Braun was likely to fire you.”
Parrish: Providing even meaningless reasons significantly increases human compliance
“Reason respecting tendency is so strong that even meaningless or incoherent reasons will also increase compliance. Psychology experiments demonstrated this. People successfully jumped to the head of lines at copying machines Simply by explaining, I have to mak…”
Parrish: Compounding psychological tendencies drive major corporate and historical outcomes
“In real life, Psychological tendencies rarely operate alone. They consistently combine and reinforce one another, creating effects larger and more unpredictable than the sum of the parts. That's what changes history. That's what builds and destroys companies.”
Parrish: Cults, sales, and politics manipulate using multiple simultaneous biases
“When you see extreme outcomes, Berkshire Hathaway's success or New Coke disasters, cult conversions, corporate catastrophes, ask what combination of tendencies created this? Be alert when multiple tendencies are being used to manipulate you. Cults have figured…”
