What does 'hard logic ' mean?

[translatorjam]

Hello, this script is from the result of MBIT test, describing INFP types.
Here, what does 'hard logic' mean? I tried to look up the definition, but they didn't have anything...
does this just mean 'difficult logic?'

- It's not uncommon for INFPs to mis-use hard logic inthe heat of anger, throwing out fact after (often inaccurate ) fact in an emotional outburst.

Thank you in advance.

No, it simple means 'logic' applied properly, just as "hard facts" simply means 'facts'.
An example of "soft logic": "It's obvious he's an idiot, because he's an ESTJ. Besides I don't like him, and he smells."
An example of "hard logic": "He may be an idiot, but that is independent of whether he an ESTJ or whether I like him or whether he smells or not."
