Intellectual arrogance

Intellectual arrogance is a set of characteristics that tends to blind an otherwise intelligence person -- OTHERWISE "INTELLIGENCE" PERSON?! Oh the irony!!!-- to recognizing the truth. These include:

• a lack of logical rigor, resorting instead to preconceived notions or what one thinks he learned in school
• a double standard to avoid admitting personal error, particularly an intellectual mistake
• a lack of humility like Isaac Newton's declaration that he understood very little
• assuming one is always correct without having sufficiently studied an opposing position
• refusing to address another's position, arrogantly assuming their argument is "beneath them"; a failure to even listen to opposing views.
• thinking you're an expert in every field.
• asserting a dubious argument is obviously true or simply follows from logic, rather than proving or providing evidence for it.

Intellectual arrogance leads to mistaken conclusions.
