Reality TV shows
Science speak: 

"The entertainment we consume can influence our emotions and behaviour" - according to the study, A Story About a Stupid Person Can Make You Act Stupid (or Smart), by Markus Appel.

What it means: 

You are what you watch and watching dumb people do dumb stuff can make you dumb too. 

Smartphones
Science speak: 

"Scientists say people who constantly multitask are more easily distracted. 

Such task-switching, aka multi-tasking, has been shown in several studies to 

increase stress, 

which can interfere with short-term memory, 

leading to more mistakes," according to a magazine. 
What that means: 

Do you feel the sudden desperation to type "whatsupp dude" to anyone on your contact list the minute your boss starts a meeting? 

Blame the smartphone. 

Thanks to it, we just don't have any attention span left. 

It also makes us think we're superhumans who can text, drive and sing all the lyrics - all at the same time. 

Isn't that evidence enough of our stupidity? 

Although there still isn't any neurological study to substantiate the fact that smartphones make us dumb, there are "distraction studies" aplenty.

Junk food
Science speak: 

Children who eat junk food grow up with a lower IQ. 

The brain grows at its fastest during the first three years and good nutrition during this period may encourage optimal brain growth. - Briston University study
What it means: 

You mean junk food makes us fat and stupid? 

sugar makes you dumb too. 

Researchers at UCLA found that rats had a harder time navigating a maze after eating a fructose-only diet.

The internet
Science speak: 

Internet and multitude of search engines

 is replacing our brains. 

Earlier we had fewer resources (ie books) to gain information and knowing we didn't have 24/7 access to those meant our brains stored the information. 

With the advent of internet and multitude of search engines, our brains no longer know how to retain the info, according to Forensic Psychology.
