If we want to limit our intelligence, the following list is a good place to start:
1) Love being right.
2) Be addicted to the moral high ground.
3) Restrict your sources of knowledge.
4) Relate only with people who are like you.
5) Relate only with people who agree with you.
Let’s acknowledge that intelligence can be a communal virtue, and work diligently to cultivate it.
