From Wikipedia, quoting a Soviet advisor after the Bay of Pigs:

"...too young, intellectual, not prepared well for decision making in crisis situations... too intelligent and too weak".

While I get that they saw JFK as indecisive, Im not really sure how to take the fact that they apparently considered him too intelligent. Perhaps from a standpoint of overthinking, but Im unsure given that would still be in conflict with their assessment of him being too intelligent for his own good.

Just seems like a poor choice of words to me. Why would someone less intelligent do better in a crisis when crisis management skills arent exactly tied to intelligence?
