When they are stronger and last longer
Answer:
Prophecy.
Explanation:
Self-fulfilling prophecy is a socio-psychological phenomenon of someone predicting or expecting something, positive or negative, and this prediction (prophecy) or expectation comes true simply because one believes it will, and their resulting behaviors align to fulfill those beliefs, including the act of predicting it (self-fulfilling). This suggests peoples' beliefs influence their actions/behaviors. The principle behind this phenomenon is people create consequences regarding circumstances, people or events, based on their previous knowledge toward that specific subject solely based on one’s interpretation of a certain situation. In this case, if the students failed previous math classes, they will fail again because they believe they are going to.
This is very true, and it is almost like the fight-or-flight response, where your body gets the adrenaline rushing and that is when you hear about people being able to lift cars and jump from 6-story buildings. It is a natural instinct of survival that we all have inside of us. Hope this helps.
