Intellectuals have the same blind spots. During COVID (At least the ones I worked with) made fun of the disease when it started spreading and refused to take it seriously, then did a complete 180 when their social circles took it seriously. And then did insane stuff like wipe down their groceries with bleach and obsessively washed their hands long after the science was clear that it spreading through the air.

No amount of intelligence will protect you from confirmation bias, authority bias, social proof, and the numerous other vulnerabilities we all have built in. Actually intellectuals are more vulnerable, since intelligent people tend to have a cognitive bias where they over-estimate their expertise in unrelated fields to their own.
