Here are two excerpts:
These two ideas – the role of arousal on our willingness to cheat, and neural adaptation – are connected because the brain does not just adapt to things such as sounds and smells. The brain also adapts to emotions. For example, when presented with aversive pictures (eg, threatening faces) or receiving something unpleasant (eg, an electric shock), the brain will initially generate strong responses in regions associated with emotional processing. But when these experiences are repeated over time, the emotional responses diminish.
There have also been a number of behavioural interventions proposed to curb unethical behaviour. These include using cues that emphasise morality and encouraging self-engagement. We don’t currently know the underlying neural mechanisms that can account for the positive behavioural changes these interventions drive. But an intriguing possibility is that they operate in part by shifting up our emotional reaction to situations in which dishonesty is an option, in turn helping us to resist the temptation to which we have become less resistant over time.
