Apparently you confused me with another commenter.

I don't think humans are irrational, and wholeheartedly agree that we are able to think logically. However, skipping all the stuff which wasn't intended for me I'd like to jump to the last sentence of your commentary to note that it hangs on a hypothesis that our actions are result of just thought processes completely detached from say metabolism, and pre-programmed reactions. I don't think its true. There's a lot of empirical evidence to claim that various things like sleep deprivation, peer pressure, level of glucose, hormons, age do affect human decision-making even if thought-information[1] remains the same. Humans btw show great ability to re-rationalize made decisions afterwards, essentially fooling themselves to believe they came to them purely by thinking.

Math is unlikely to be affected by this, but politics, relationships, and a lot of other decisions - easy.

[1] Technically, hormons, and instincts are information inputs as well, but they are usually processed outside of concious thinking.

EDIT: added the last para.
