1. Self-fulfilling prophecy means that a belief or expectation about the future can influence our behavior in a way that eventually makes that expectation come true.

2. The concept is strongly associated with sociologist Robert K. Merton, who popularized the term in 1948.

Example 1 : learn Math

Imagine a student thinks:

“I’m bad at mathematics. I’ll never understand it.”

1. First, a person starts with the belief, “I am bad at math.”

2. Because they believe they will fail anyway, they avoid practicing or giving it real effort.

3. When the test or assignment comes, they naturally perform poorly because they didn’t practice.

4. Finally, they look at their low score and conclude, “See! I knew I was bad at math.”

5. The belief itself caused the behavior that made the belief come true.

Example: 2 Understand Subject

1. You start with: “I can understand difficult subjects if I give them enough time.”

2. You don’t understand Plato on the first reading. But because you expect yourself to improve, you reread, make notes, ask questions, and practice explaining it.

3. After a few months, you actually understand difficult texts better.

Example 3. Public speaking

1. A person thinks: “I can become a good speaker through practice.”

2. They start speaking even though they are nervous. They record themselves, notice mistakes, and practice again.

3. After six months, they speak much more confidently. The original expectation encouraged the behavior that produced improvement.

🧠 Remember it this way

What you expect can influence how you behave, and how you behave can influence what happens.
