Nah, that's not how you debias, you mostly doing by practicing calibration (give odds for things and then checking what proportion of the 90% probability things actually happened).

The reasoning improvements primarily cone from a greater awareness of words (ambiguous meaning, context sensitivity, considering things as if they were statements in set theory) and tools like word tabooing or outside view.

I doubt the author has had much contact with rationalists (who the hell says "rationslism"?!).
