Okay, imagine you're playing a game and you have to choose between two presents. Let's call them Present A and Present B.
You have no idea what's inside each present, but you have to choose one of them.
Now, let's say your friend knows what's inside the presents and they tell you that there's a toy car in Present A.
Because you want a toy car, you might think that you should definitely choose Present A. But here's where the principle of restricted choice comes in.
Just because your friend told you about the toy car in Present A, it doesn't mean that Present A is automatically the best choice.
What if your friend didn't tell you about the really cool puzzle that's inside Present B? You might actually like the puzzle more than the toy car, but you wouldn't know that because you're only considering Present A.
So, even though your friend restricted your options by telling you about the toy car in Present A, you should still consider all of your options before making a decision.
That's basically what the principle of restricted choice means - don't automatically assume that a certain option is the best just because you have information about it. Always consider all of your options before making a decision.
