A short YouTube video (by James Laughlin) about negativity bias: Speaker A explains that the brain habitually focuses on negative thoughts as an evolved threat-detection mechanism, often causing people to overweight isolated negative comments or events in their day. The excerpt emphasizes frequency estimates of thoughts and how modern, non-lethal stimuli are misperceived as threats.
How does the negativity bias actually function? Yes, it's like we have, like you say, 60 to 80,000 thoughts on average per day, and 80% of those are negative unless we do something about it. Because that's just purely because our brain is trying to look for threats to keep us alive. And like I said today, what it was scanning for before, like a tiger coming out of the bushes, generally going to, like, you know, attack you, it's now scanning and just finding these modern threats that aren't going to kill us, but it still sees them as a threat. So, you know, even when a comment upset you from a friend, your brain will, you know, you come back from the end of the day. The example is, you know, your loved one says, how was your day? And one comment that one person made that was probably like, you know, 1% of your entire day's conversations, your brain will remember that one comment like, oh, I didn't have a very good day, actually. That's probably not in the grand scheme of things, you know, so this is how our brain latches on.
