My observation is that people mostly think at the same speed but some are happy thinking less before they draw conclusions. This often comes across as a skill or being smarter (to be fair it's a legit skill whether you agree with the results it delivers). I find a lot of business and management consulting is like this, people happily jump to the closest pattern whether or not it fits in order to avoid thinking and appear clever, and there's very little appetite to actually think deeply about something because whatever you do will need to be run by other people who don't want to think...

I agree. And when this tendency fuses with overconfidence and obstinacy, it becomes the root of much of the world's problems.
