[illivah]

Here is the difference:

If you try to replicate a fact, you'll succeed If you try to disprove a fact, you'll fail If you find rebuttles to a fact, they'll be hollow

The only thing in the obvious list that doesn't separate a fact from a non-fact is the arguments in support. Hence why scientists are taught not to care for arguments in support, only research, and then specifically arguments that disprove more than those that prove.
