Sometimes worry does not arrive from the outside. We generate it ourselves, through patterns of thinking that feel reasonable but are actually making things worse. Researchers at two top American universities ran an experiment. They gave people a range of scenarios and asked how likely each would make them to change their travel plans. One scenario was a real plane crash on the same route. Another was simply dreaming about a crash the night before. The result was striking: dreaming about a crash made people almost as likely to rearrange their plans as a real one. The mind treats vivid imagined events as genuine threats. This is how several common thinking traps work. Feeding your fears: you rehearse the worst-case outcome so many times, in such detail, that it starts to feel more likely than it is. Playing the victim: you give external events complete power over your emotional state and tell yourself you have no choice but to feel bad. And a subtler trap many people fall into: forcing positive thinking. You tell yourself everything is fine when you clearly do not believe it. This performance is exhausting and can actually deepen anxiety, because you are adding a layer of dishonesty on top of an already difficult feeling. The exit from these traps is not more positive thinking. It is honest, rational thinking.
