Today I realised that the best way to guard against group think is to test your idea vis-a-vis people who are completely ignorant of the field.
These folks with common sense will tell you which assumptions are completely stupid or “unknown” to the masses. And from there, you’d know your competitive advantage over the average person.
Therefore, rather than being “against” group think, I’d say that group think does limit one’s knowledge of his own competitive advantage. For, If I don’t know my strength, I can’t be as confident as I could otherwise be.
It’s so important to map out what people don’t know that they don’t know, but YOU know that they don’t know! 😀 😀 😀
