"I'd agree with Rocky and Phaedrus on this one; in Socionics, ILI is the one who's more like to promote provisional theories, whereas LII is the one who will attempt to say only what he's sure is true. "

I think you misunderstood me; I agree the LII will, more likely than not, only state that which he believes to be true beyond a doubt, but so will an ILI---the matter of fact is, though, that an ILI is more keen to believe or disbelieve something based on less evidence than an LII. Rocky's father, though not neccessarily INTp, exhibits many INTp-like behaviors when he exhibits firm conviction in what he states.

And Phaedrus, that's a long time ago; I've changed a great deal.
