14 statements about Mental Models, every show
Ng: Use A/B testing to hone gut instincts, not just pick variants
“I don't just use the result of A-B test to pick product A or product B. My team will often sit down and look carefully at the data to hone our instincts, to speed up, to improve the rate at which we're able to use the first tactic to make high quality decision…”
Larson: Half of metrics' value is educating leadership mental models
“I think people want metrics to show reality. They want to show the truth, but half of metrics is showing the truth. The other half is educating people to inform their mental model about how the truth works.”
Rao: Mental models are best understood as fictional world-building
“The best definition of a mental model is a world in the sense of science fiction or fantasy, right? So you've got, say, a universe like the Harry Potter universe or the Lord of the Ring universe, and so there's the world, and then there's the story that's told…”
Klein: A complete mental model requires four distinct components
“My idea of a mental model started out with how something works. And now it includes all four of these components, how it works, what its limitations are, how to work around them, and how to anticipate confusion on the part of people who I'm going to be working…”
Cain: The Value of Teaching Mental Models Is Driving Execution, Not Awareness
“Compound interest, inversion, stuff that you already know, but like people aren't doing it. How do you lose weight? Exercise more, eat less, but it's getting people to do that that's the interesting challenge to me. That's where teaching is. It's taking people…”
Hamilton Helmer: Strategic mental models must be simple, but not simplistic
“The bar for effective mental models is that they are simple but not simplistic, because if they're not simple, you can't retain them. Easily. And you can't use them. If they're simplistic, then you miss important stuff. So it's got to be exhaustive, not simpli…”
Decoding mental models requires tuning into physical sensations over rationalizations
“Then I think what you have to do is you have to get beyond the rationalization to the physical experience. What I mean by that is when we are interacting with the world, we are having a sort of whole body experience with that interaction. We feel things. So wh…”
Confusion is a necessary tool to learn and update mental models
“Confusion is indicative of the fact that you are having an experience that's different than what you expected. And that confusion is necessary to start to make sense of the world yourself and the connection between the two.”
Page: Organizational efficiency pressures erode cognitive diversity in mental models
“When I go work for a firm, or if I'm working in an organization, you know, stock analyst, psychologist, whatever I'm doing, mental models that we use are like local interaction models. Right? I mean, like, it's like, oh, you're using that metal model. It's eas…”
Heffernan: Mental and economic models inherently repel disconfirming data
“And the problem with mental models, also business models, also economic models, is they attract confirming data, and they repel marginalized or trivialized disconfirming data.”
Rao: Mental models are best understood as fictional world-building
“The best definition of a mental model is a world in the sense of science fiction or fantasy, right? So you've got, say, a universe like the Harry Potter universe or the Lord of the Ring universe, and so there's the world, and then there's the story that's told…”
Rao: Mental models prioritize internal consistency over reality
“I don't think really mental models are so much about how the world works as much as they're about internal consistency.”
Rao: The primary purpose of a mental model is to blind you
“So your mental model's job is basically to blind you. It's to blind you to 99.9999% of all the pertinent reality data that could possibly be salient to a decision so that you're paying attention to an extremely narrow stream of information. That's the purpose …”
