Our brains are limited in many ways. We need time to process incoming information. For evolutionary reasons, we've developed shortcuts that allow to make snap decisions when needed. However, these shortcuts come at a cost in accuracy. When we use these shortcuts and never take the time to reconsider, we're often left believing in falsehoods. Often these beliefs go unchecked for long periods and our conviction in them can be very strong. By understanding how these biases work, we can strive to course correct when our snap decisions are off target.
