In a lack of other data, you will fall into judgment by symmetry

The statement "In a lack of other data, you will fall into judgment by symmetry" suggests that when we are presented with limited information or knowledge about a situation, we tend to make judgments based on what we know or perceive to be symmetrical or balanced. This tendency towards symmetry or balance is a cognitive bias known as the "law of symmetry," and it can influence our decision-making process. When faced with incomplete information, we often fill in the gaps by assuming that the missing information is consistent with what we already know, or what we perceive to be symmetrical or balanced. For example, if we see two people in an argument but only hear one side of the story, we may automatically assume that the other person is equally at fault or that there are two sides to the argument, even if we don't have all the facts. This cognitive bias can be problematic because it can lead to incorrect assumptions and judgments. It's important to be aware of this bias and try to gather as much information as possible before making a decision or passing judgment. We should also be open to new information and perspectives that may challenge our preconceptions and assumptions.
