This is a lovely piece on an expansive view of intelligence and all the things that influence it.
The over-arching theme is that intelligence isn’t fixed and is largely situational.
The author draws out certain themes from the literature which influence how intelligent we are going beyond the standard, expertise and including, what emotions are at play (negative emotions kick in the “flight” response, so it’s hard to be so smart), what relationships exist and our own mindset.
To my mind, this has great value for managers in that it reminds us that we can to much to support our team’s collective intelligence by creating the right conditions to the extent we can.
What I would add for my two cents is that we can be made more intelligent by supportive challenge and also by being made to explain our topic for a specific audience.
