Negativity bias is our brain's tendency to pay more attention to potential threats, problems and negative experiences than positive ones. From an evolutionary perspective, this helped our ancestors survive. Missing a threat could be dangerous, while missing something pleasant usually wasn't. The challenge is that our brains still work this way today.
It can show up as:
• Focusing on what went wrong rather than what went well
• Remembering criticism more than praise
• Assuming the worst when information is unclear
• Dwelling on mistakes long after they happen
• Looking for signs that something is wrong in our relationships
In relationships, negativity bias can be particularly powerful. Your partner may have been supportive all week, but one frustrated comment becomes the thing that sticks. You might overlook the small acts of care and instead focus on what wasn't done, what wasn't said, or what could go wrong. Over time, this can leave both partners feeling misunderstood and disconnected.
One of the biggest misconceptions about therapy is that it's about getting rid of negative thoughts. It isn't. Thoughts are a normal part of being human. We cannot stop our brains from producing them. Using approaches such as Cognitive Behavioural Therapy (CBT) and Acceptance and Commitment Therapy (ACT), I help clients become more aware of their thinking patterns and, importantly, learn what to do after the thought shows up. Rather than automatically believing every thought or getting caught in a spiral, we learn to respond more intentionally.
Sometimes the most powerful change isn't changing the thought itself, it's changing your relationship with it.
