He is a lecturer at the Experimental Psychology Department of Eötvös Loránd University and at the business school Kürt Academy. He is also a founder and leader of a software company producing computer games. One of his projects is a computer game he is developing with Ernő Rubik, the inventor of the Rubik's Cube. He is also the leader of the Hungarian team at the World Puzzle Championship. His son is Csaba Mérő, 8 time Hungarian go champion. He represented Hungary in the Tenth International Mathematical Olympiad held in Moscow in 1968, and was awarded a Bronze Medal. He graduated from Eötvös Loránd University with a degree in Mathematics in 1974. He spent the next ten years at the Computer and Automation Institute of the Hungarian Academy of Sciences, working on various pattern recognition and artificial intelligence projects. Recognizing the limitations of artificial intelligence, he began investigating human cognition. Since 1984 he has been at the Experimental Psychology Department of Eötvös Loránd University, studying cognitive psychology and psychophysics. He has written two books, Ways of Thinking (newer translation: Habits of Mind) and Moral Calculations, that aroused the interest of the wider, non-professional public. His books analyze the quasi-rational mechanisms of people and the nature of rationality in general, undermining some common beliefs about our minds' functioning. He has been publishing in Magyar Narancs a series titled Are you the dance instructor here? (The title refers to a joke: A client enters the dancing school and asks a well-dressed man: "Are you the dance instructor here?" "Fuck no, I'm the etiquette instructor!") Several of these essays were collected in a book in 2005 (see below).
