Hi @galenkp, one of the points of the publication I will add it to my work tools: Go backwards. I find it quite interesting and I think useful.
The point of meeting and dialoguing with different people, not only I think it is very necessary, but I understand it in the broadest sense: reading books with opposite points of view to ours, dodging the bubbles created by algorithms on the internet and looking for different opinions to ours. This, I think, helps to think, or to rethink for some people.
The examples you give about doing different things, such as using the non-dominant hand to do some tasks, are very interesting. The "science" supports these types of behaviors. I don't know if they are useful to be smarter, but they are very useful to avoid cognitive impairments.
Out of curiosity, I am just finishing reading a book by Nardone on what he calls strategic stupidity, in which he describes several profiles of stupid people, surely none of these people apply the points you make.
I hope this Thursday is being a good day.
