Surprise birthday parties, spontaneous trips and unexpected visitors are often portrayed as exciting experiences. But not everyone feels that way. Some people genuinely dislike surprises, no matter how positive the intention behind them may be. They prefer knowing plans in advance, understanding what is coming next and mentally preparing themselves for situations. Psychology suggests this does not automatically make them rigid, controlling or boring. In many cases, their brains may simply process uncertainty differently.
Researchers have discovered that humans are prediction machines. Our brains constantly work to anticipate future events so that we can conserve energy, reduce stress and maintain a sense of control. When that system is disrupted, some people feel more uncomfortable than others. Several psychological theories help explain why.
