Psychic distance is a big word that means how different two things feel or seem to you. For example, how different it feels to go to a place that's nearby versus a place that's really far away.
When you think about something that's close to you, you feel like you understand it pretty well. You know what it looks like, how it feels, what it smells like, and so on. But if you think about something that's far away, you might not know much about it. It might seem really different from what you're used to.
Psychic distance is like a measure of how far away something feels to you. It can be influenced by things like the language people speak, the customs they have, and the way they think about things. So even if two places are physically close to each other, they might feel really different to you because of these other factors.
For example, if you live in the United States and you think about going to Canada, it might not feel like that big of a deal. After all, they speak English there and the culture is similar in some ways. But if you think about going to China, it might feel really different because the language and customs are very different. So even though Canada and China are both far away from the United States, they might feel like different distances from you because of these other factors.
