Please could you define what you understand by “high logic”?

Personally, I’m only familiar with “higher-order logic” as defined in maths. So for me, someone with “high logic” has the ability to interconnect and solve complex problems, which is one of the key skills measured by IQ tests.

Realising your beliefs and reality do not align doesn’t require complex logical reasoning, so for me the statement you quoted doesn’t mean high logic.

Your bias is showing. Intelligence isn’t necessary to be left wing. Change is hard for everyone and requires emotional intelligence, not IQ.

Would you mind sharing more details on your experience?

Like, was it a single person that got you thinking, or feedback from a group?

Is there a particular conversation that you remember as the start of change, or rather a gradual shift over time?

Did/was something happen(ing) in your personal life at the time that made you more open to hearing another opinion?
