We humans have many biases, but one that often asserts itself is the negativity bias, or a propensity to select, or attend to negative instead of positive information. We often expect the worst. We do this so the worst won’t happen, or so we can take steps to avoid it.
But often, the bias can do the opposite, and lead us to inaction. It can cause depression, or a sense of powerlessness. We can tell ourselves we can’t do anything to avoid whatever we fear will happen or to stop the dismal future we fear is inevitable??? even when the only thing making it inevitable is our inaction. We might hide from feeling the reality of the danger because we fear that even the thought is too much to bear; but the reality would be so much worse to face.
