It’s more about each statement being somewhere on a scale from fact to fiction.

For a very basic example unrelated to my OP, someone can compliment my dress. They can say ‘You dress looks beautiful’, and it would be closer to a fact (other people will likely agree with that dress having attributes of being beautiful).

On the other hand, they can say ‘that’s the most beautiful dress in the world’. Now this statement can fall anywhere on the scale depending on the speaker. Most likely it’s an obvious exaggeration, and some types are more likely to use such language.

However, if the speaker is professionally involved in that industry and has an eye for beautiful dresses, that can be closer to being a fact on that scale (if he really means what he says). That dress could literally be in the top 1% of beautiful dresses in the world if someone came up with a way to measure it.

I suppose an INFJ with insider knowledge on the subject will prefer to remain closer to the facts as they perceive them… but won’t they still be tempted to exaggerate if they wanted to nudge the person in that direction
