Rosi’s Guests: Why Vegan isn’t just Baloney to us
Rosi’s pub in Trier is doing well – until suddenly more and more vegetarians and vegans start showing up. So she decides to offer plant-based dishes alongside her chicken wings and schnitzel. But then the mood among the guests escalates. What’s going on? Luckily, I’m not just a waiter in the pub, I’m also a psychologist. And so the search for clues begins.

Rosi’s Guests: The Meat Paradox
There is confusion in Rosi’s pub in Trier: some guests suddenly don’t want to eat meat anymore. What’s going on? Rosi asks me for advice. Luckily, I’m not only a waiter, but also a psychologist. So I embark on a journey into the psychology of meat eating – and come across the so-called meat paradox.

Rosi’s Calculation: Psychology for the Gastronomy
At Rosi’s pub, schnitzel and chicken wings are always popular. But then: chaos in the kitchen. Sometimes everything is left over, sometimes everything is gone immediately – even our meat fans suddenly only want chips. Rosi says: “That’s not right!” And me? I say: maybe it is. Because in social psychology, we know that it is often not the person who changes, but the situation. And sometimes a tiny trigger that reminds us that life is finite is enough to influence our decisions. What does this have to do with meat? Welcome to terror management theory.

Unleashes the Tiger in You: The End of All Flesh
‘They awaken the tiger in you’ – that’s how breakfast cereals used to be advertised. But what about the rest of breakfast? Does that ham sandwich influence us as well? Indeed, meat can remind us that we are animals. And worse still: that we are mortal. Sounds far-fetched? Not for social psychology. It says that when we become aware of our own mortality, our behaviour can change, often quite unconsciously. Welcome to terror management theory.
