Mental Models

Ventakesh Rao offers a comprehensive definition of mental models, describing them as sets of beliefs, desires, and intentions. He compares them to fictional universes like Harry Potter and Lord of the Rings, where understanding the world is crucial to following the story. This analogy helps illustrate how mental models function in our daily lives, allowing us to efficiently make sense of complex information 1.

Mental models allow you to very efficiently make sense of stories. And if you are not familiar with the mental model, then the author must build the mental model.

Rao also highlights the challenges of understanding foreign mental models, using Japanese comic books as an example of how different conventions can make comprehension difficult 2.

   

Conceptual Reasoning

Conceptual reasoning is another key aspect of decision making, as explained by Ventakesh Rao. He identifies three major decision-making styles: conceptual, ethical, and affiliational. Conceptual reasoners use mental models and metaphors to frame their decisions, while ethical reasoners rely on a deep sense of right and wrong, and affiliational thinkers base their decisions on group dynamics 3.

What narrative is sort of framing the unfolding of events? So that's an approach that's very natural to me.

Annie Duke adds that strategic decision making often involves both individual execution and group collaboration. She emphasizes the importance of deconstructing decisions with peers to refine strategies and improve future outcomes 4.
