From Buddhas Brain
“The brain typically detects negative information faster than positive information.
Take facial expressions, a primary signal of threat or opportunity for a social animal like us:
fearful faces are perceived much more rapidly than happy or neutral ones, probably fast-tracked by the amygdala (Yang, Zald, and Blake 2007).
In fact, even when researchers make fearful faces invisible to conscious awareness, the amygdala still lights up (Jiang and He 2006).
The brain is drawn to bad news.”

My two cents: I have also read that the mind can sense danger even if it is hiding behind a post in a room.
Knowing how the brain prioritizes events, how the nervous system and defense mechanism fires, help us navigate PTSD.
Intuition, our wisdom without cognition, flows from our right hemisphere of the brain.
Like looking down a dark alley, you sense danger.
My advice listen intently and avoid the alley.
In my opinion, intuition is far more reliable than any cognitive function we possess.

The brain has a negative slant
We need to be more positive just to reach equality
Negative is like velcro and positive like teflon
We always slow down and look at the wreck on the freeway
News is all negative, sensational
Doing normal activities even great kindness rarely makes the news

The prime-time news offers the human a cheap fix of sensationalism. I believe that is in part, an explanation for reports that center on attention-grabbing vocabulary rather than real, unadorned facts. I avoid a lot of public news stations and ‘entertainment.’ Heightened alert is NOT what my PTSD requires.
