Anticipation can only be built.....

..... by leveraging the inbuilt curiosity of human nature. Now, the question is what invokes that curiosity.

1. When you see or hear about something usual. That's why conspiracy theories and haunted stories work.
2. When you feel FOMO. You hear about something a few times from others, but you have no clue what it is, so to fit in you look for it.
3. When you had an inherent need or want that was unmet, and then one day you stumbled upon a rumour that someone is building a solve for it.
4. When you hear words from someone that you always had in your thoughts, but were too scared to say them.
5. When someone confirms your bias.
6. When you find out that things are different in nature then they appear. Now you'd like to know why.
7. When something or someone in front of you is mysterious, you can't decode or judge it for sure, what is it?
8. If you keep hearing or seeing something or someone frequently.

Comment if you know some more.
