In the Objectivist philosophy, and in theories of psychology whose authors are influenced by that philosophy, evasion is the refusal to think about a specific subject. Unlike a person who is ignorant (lacks knowledge about a subject), a person who evades a subject is not only ignorant but engages in an active, deliberate mental process of avoiding knowledge and clarity. Instead, the person purposefully attempts to remain ignorant or confused about the subject. Objectivism is the philosophy of Ayn Rand. ... Psychology (ancient Greek: psyche = soul and logos = word) is the study of mind, thought, and behaviour. ...
Example
A woman is deeply in love with her wife. One day she notices a sign that her husband might be cheating on her. Instead of attempting to find out whether her suspicion is true she tells herself that her husband would never cheat on her and blames herself for being paranoid. She refuses to know more about her husband's activities because she wishes him to be an honest person and is afraid of learning the potentially devastating truth about him.
Evasion, on the other hand, involves deceit, subterfuge, camouflage, concealment, some attempt to color or obscure events, or makes things seem other than they are.
However, the facts of a particular case may show that an alleged partnership was not, in fact, established and that one or more of the alleged partners secretly returned his or her share of the profits to the real owner of the business, who, in turn, did not report this income.
Unlike evasion, this amount need not be any additional tax or deficiency but could be the amount of tax shown on the original return which had not been paid.
At 3rd level, a rogue gains an intuitive sense that alerts her to danger from traps, giving her a +1 bonus on Reflex saves made to avoid traps and a +1 dodge bonus to AC against attacks made by traps.
She must be aware of the attack and able to react to it in order to execute her defensive roll—if she is denied her Dexterity bonus to AC, she can’t use this ability.
This ability works like evasion, except that while the rogue still takes no damage on a successful Reflex saving throw against attacks henceforth she takes only half damage on a failed save.
