According to behavioural plasticity theory
◦ the best way to change people's behaviour is to use external and social influence.
◦ people's behaviour will only change when their self-esteem is threatened.
◦ people with low self-esteem are more susceptible to external and social influences.
◦ people's self-esteem can easily be changed in response to external and social influences.
◦ people with high self-esteem are more likely to benefit from external and social influences.
