Your brain is Velcro for bad news and Teflon for good
One insult outlasts ten compliments in memory, and the psychologist Rick Hanson has a name for why.
Rick Hanson, in Hardwiring Happiness, borrows a pair of household materials to describe an asymmetry most people have felt but never named: the brain snags on negative experiences and lets positive ones slide right through. A single sharp criticism can occupy your evening. A sincere compliment rarely gets five seconds.
The mechanism is evolutionary, not personal. For most of human history, missing a threat could kill you; missing a nice sunset could not. So negative events get fast-tracked into emotional memory on contact, while positive ones need to be held in attention for several seconds running before they encode at all — and almost nothing in daily life makes us hold still that long.
Hanson's practical move, which he calls “taking in the good,” is almost comically small: when something pleasant happens, stay with it on purpose for ten or twenty extra seconds instead of letting the mind move on. It won't erase the negativity bias. It just gives the good moments a fighting chance at becoming Velcro too.
