Cognitive biases are assumptions and judgments and error that our brains automatically make without us even knowing it’s happening. They are like automatic mental shortcuts. But the problem is: they could be messing with your marriage without either of you even realizing it!

We have a brainy episode for you this week.  We’re going to be talking about cognitive biases in marriage. This is about how your brain gets in the way of your connection with one another, and how to deal with that.

What Is Cognitive Bias?

As we pointed out in the intro, biases are assumptions, judgments and errors which our brains automatically make without us knowing. Often they are "shortcuts" the brain takes to help us process information and make decisions more quickly. Biases are not necessarily bad nor are they a sign of mental illness (although they do get stronger when we are stressed or experiencing anxiety/depression), and often they are useful[i].

But sometimes they can influence our thinking in unhelpful ways without us knowing. These biases can impact all areas of life, including marriage. So it’s good to know about them, why they happen, how they affect us and what to do about it.

The Spotlight Effect and The Illusion of Transparency

What Is This Cognitive Bias?

The spotlight effect is "the tendency for people to overestimate the extent to which they believe that others see and attend to their external appearance"[ii]. Essentially it means you expect people to notice things about you (like how you look) and notice things you do (both good and bad) far more than they actually do.

This was originally tested by a study done in 2000[iii] by asking study participants to walk through a crowded cafeteria while wearing an embarrassing t shirt. The participants expected that everyone would notice them and judge them for wearing a silly shirt, but in actual fact hardly anyone noticed or cared. That’s overestimating the extent to which others notice your appearance.

The illusion of transparency is similar, but to do with our thoughts rather than our outward actions. It is the "tendency for people to overestimate the extent to which their internal thoughts, feelings, and attitudes ‘leak out’ and are seen by others.[iv] We expect others to be able to read our thoughts and emotions a lot more clearly than they actually do. This is also sometimes called the "mind reading bias" because we expect people to be able to read our minds much more accurately than they really can.

Why This Happens

Our actions, thoughts and appearance are always obvious to us than to others. So when we do something embarrassing we expect it to be just as obvious to everyone else. Equally, if we do something good or succeed at something, we expect everyone else to notice and can become annoyed when they don’t. Or when we see something a certain way, it is abundantly clear to us and we expect others to be just as lucid.

How This Cognitive Bias Affects Marriage

These two effects can lead to increased anxiety: thinking that your spouse is scrutinizing your appearance and thoughts can lead to high anxiety and over-compensating by trying to mask your emotions. Eg "I have to look my best all the time or my spouse will notice and think I'm not making any effort" or "If he/she notices I'm upset it will upset him/her too, so I need to make sure it doesn't show"

They can lead to feeling unappreciated: thinking that your experiences are obvious to your spouse can leave you feeling unappreciated when they don't react. Eg "He didn't even notice my new hairstyle" or "I was obviously upset and he/she didn't even ask why"

They can also contribute to poor conflict resolution. Thinking that your grievances are obvious to your spouse can lead to conflict avoidance or passive-aggressive behavior. E.g., "I shouldn't have to tell him/her why I'm upset! it should be obvious!"
