ELI5 Why do our personal tastes differ?

Like, why does one person like chocolate but the other vanilla? Why does one person like pink and another blue? I understand genetics and how you are conditioned as a child play roles, but can one say more?

Our preferences and tastes are subjective to our own bodies and experiences. If you live in a country that has a lot of spicy food, like India or Mexico, you are more likely to develop a taste for such spicy foods.

As you said, genetics and hormones can also play a part. If you react painfully to chili peppers, you will grow to dislike spicy foods.

In a more general sense, out tastes are pretty random, because our bodies are random, our minds are random, and our situations are random. So, while shared traits can lead to reasonable predictions, like little boys in America favoring blue over pink because "girls toys" are colored pink, there is no set mechanism that will force or prevent a little boy from liking pink anyway.
