Neuroscience of Habit Formation: Research by Dr. Ann Graybiel at MIT has shown that habits are deeply ingrained in neural pathways, making them resistant to change. Part of the brain called the amygdala, which detects danger and controls our flight or fight response, sees change as a threat. Sometimes the thing you want to change is something you’ve been doing most of your life. The brain's reward system reinforces habitual behaviours, making it difficult to break free from established routines. 

Cognitive Dissonance Theory: According to Leon Festinger's theory, individuals experience discomfort when their beliefs or behaviours are inconsistent with those around them. This creates resistance to change, as people try to maintain internal consistency and also avoid discomfort.

Fear of the Unknown: Psychologist Kurt Lewin's Change Theory emphasises that individuals often fear uncertainty and the unknown outcomes associated with change. This fear can lead to resistance, as people may prefer the perceived safety of their current situation over the uncertainty of change.
