We all make hundreds (maybe even thousands) of decisions every day. So, you'd think we'd be expert decision-makers by now! But far from it. In fact, I'd argue that decision-making is becoming harder (or at least more complex) as a result of modern life – partly because the world is now so fast-paced, requiring us to think and act faster than ever, and partly because we have more information than ever before, making us prone to information overload. These factors complicate our ability to make good decisions, very often leading us to oversimplify things and take mental shortcuts.
