How to Build a Happier Brain

Ever wondered why it’s so easy to focus on negative experiences and yet we cannot seem to recall happy times without feeling anything more than nostalgia? Doesn’t it seem that our brain has a hard time registering good experiences and yet it’s so efficient in storing the bad ones?

The following article has an interesting theory: http://www.theatlantic.com/health/archive/2013/10/how-to-build-a-happier-brain/280752/

From the article:

As our ancestors evolved, they needed to pass on their genes. And day-to-day threats like predators or natural hazards had more urgency and impact for survival. On the other hand, positive experiences like food, shelter, or mating opportunities, those are good, but if you fail to have one of those good experiences today, as an animal, you would have a chance at one tomorrow. But if that animal or early human failed to avoid that predator today, they could literally die as a result.

That’s why the brain today has what scientists call a negativity bias. I describe it as like Velcro for the bad, Teflon for the good. For example, negative information about someone is more memorable than positive information, which is why negative ads dominate politics. In relationships, studies show that a good, strong relationship needs at least a 5:1 ratio of positive to negative interactions.

Positive experiences use standard memory systems: moving from short-term buffers to long-term storage. But to move from a short-term buffer to long-term storage, an experience needs to be held in that short-term buffer long enough for it to transfer to long-term storage—but how often do we actually do that? We might be having one passing, normal, everyday positive experience after another: getting something done, look outside and flowers are blooming, children are laughing, chocolate tastes great, but these experiences are not transferring to storage or leading to any lasting value.
