I agree with you here. I don't buy a connection between the inability to say I don't know and cheating. If anything I'd think it were an inverse relationship, based on my own humble experience. I used to be too insecure to say I don't know and would often ramble to cover my deep embarrassment of not knowing. That being said the same acute sensitivity to embarrassment also ensured I never cheated on anything in my life - the terror of the embarrassment of being caught cheating far outweighed any potential gains.
