Liking

We say yes to people we like, and we like people who seem warm, genuine, attractive or similar to us, so likeable faces sell.

Liking: where it comes from

People rate strangers who share their opinions as more likeable, as Donn Byrne showed in early studies of attraction (Byrne, 1961). Liking is one of Robert Cialdini's principles of influence: we say yes more easily to people we like.

In ads it shows up as warm, funny, genuine or attractive people and characters, and as people who seem just like the audience.
