 The second psychological hack is the cheerleader effect. What looks more appealing? A lonely cup of coffee or a coffee with a muffin. This is a very powerful tactic that makes your offering much more appealing. Most of the items in Starbucks are presented in groups and that's because individual items look more attractive when they are presented in groups. Rather than focusing on the individual characteristics of the item, we focus on the feeling as a whole. So what is that opportunity for you? Well, if you're selling beverage instead of just showing one, show it in groups of three. If you're selling a meal, show it with wine, show it with side dish. This makes this whole experience much more pleasant as well.
