Our brain is an excellent thinking apparatus that we can use to accomplish a variety of life tasks. However, we all experience situations in which we don't think and act quite rationally: we stick with our overpriced phone plan even though there are significantly cheaper offers, we treat ourselves to an extra serving of potato chips because we've been exercising for half an hour, or we come home with our fifth pair of sneakers from the summer sale even though there is no more room for it on the shoe rack.

Such situations do not arise randomly, but can be traced back to systematic, faulty thinking patterns: cognitive biases. Our brains keep unconsciously luring us into these thinking traps, which contribute to our inability to perceive and judge our environment completely objective.

»biased« was my graduation project at Hochschule Mainz. It is an encyclopedia that offers an explorative overview of the most significant cognitive biases, aiming to raise awareness of how our thinking and decision-making are often less rational than we assume.
