Foot-in-the-door phenomenon
Explanation:
According to my research on studies conducted by various psychologists, I can say that based on the information provided within the question Jackson's experience illustrates the Foot-in-the-door phenomenon. This is a phenomenon of someone's willingness to perform a large unethical task/behavior after having done a smaller unethical task/behavior. Which in this situation Jackson shoplifted some video games, since there was no consequence for that action he was more willing to later steal the neighbor's expensive racing bike.
