Joshua Green has a piece in Wired about a four week to get smarter.
But is real cognitive improvement possible? Experts say yes; intuition suggests no
"I also learn (more) about the wonders of coffee. Caffeine sharpens the senses and quickly increases performance, as one neuroscientist demonstrated by steering me to an addictive online game called Sheep Dash! As sheep dart across the screen, you shoot them with tranquilizer darts as fast as possible by clicking your mouse. The game measures response time, then instructs you to have some coffee and try again. My morning mug makes me about 5.5 percent faster. Extremely cool. Work productivity plummets."
I am a sucker for cognitive improvements so I am going to try Joshua’s exercises.
