We have a massive cortex bigger than the rest of the brain. The human cortex in fact can overrides some functions of the rest of the brain.
This is not true for most of other animals.
My point is this: overcoming instinct is possible because of the way our brain is organized (this however requires some training, as we actually do in order to survive into adulthood) and because it is a positive trait.
The fact that this is not more prevalent indicates that perhaps overcoming instinct is not really that positive (the limbic system with its feelings and hunches probably helps detect cheating in a more straightforward and efficient way than deep thinking about it).
