The best way to achieve this is to use something called 'cognitive behavioral therapy'.
If this brought positive reward, that would then be a form of positive reinforcement that could condition them to behave this way.
The very stereotype of short man syndrome meanwhile might lead their behaviors to be perceived as stemming from their insecurity.
A cohort in the experiment would constantly rap the participants on the knuckles, and the elevation of the participants' heart rates were then measured.
This found that those who were shorter were actually more calm and more likely to maintain a steady heart rate.
However what this study neglects to take into account is that short man syndrome is used to describe a specific and unusual level of overcompensation.
