Does the Computer Make Us Dumb?
"We have become a gadget-happy generation, but the gadgets make us dumber, not smarter. You had to know something about math and logarithms to use the old slide-rule, anybody can use the new pocket calculator."
Presently, anyone who has access to the internet either through a personal computer, laptop, android, or smart phone can easily post "bits of wisdom", quotes, memes on Facebook for everyone to see and read. Some can easily go viral with hundreds of likes and shares in less than an hour. If calculators of decades ago affected our math skills, are the gadgets of this age affecting our ability to write, read and think? An article by Michael S. Rosenwald in the Washington Post raises this issue.
The suggestion that calculators made students incapable of doing simple arithmetic is wrong. The suggestion that the internet is making us dumb is likewise wrong. Although the brain has enormous plasticity, it does not change dramatically. Basic education, for example, takes several years at least a decade.
There are studies that have compared how well we comprehend when reading on screen versus when reading on print. The following shows that reading on screen leads to less comprehension:

The last sentence of the above abstract perhaps captures the truth. It is human behavior. And a study in Israel demonstrates this quite convincingly:
Gadgets allow us to be lazy. Critical reading requires hard work. Facebook, for example, allows us to share ideas, news, views and opinions as quickly as a click on a mouse. It is effortless. It is also easy to find only the things we like. There is no need to vet since it is not difficult to find others who share our views. It is easy to have the illusion that we are experts since the cost of publishing one's view is now close to zero. In fact, sound bites are better, copy someone else's quote, post it, and we feel intelligent.
Calculators and the internet share one thing in common. These are tools that have indeed empowered humanity. I like both. These do not rewire our brains. What these gadgets do, however, is to simply highlight something we already knew. We like shortcuts and we do not like hard work. We like trends and we do not like careful thinking. We like sound bites and we do not like heavy articles.
