What is smart? Some people judge smarts by standard benchmarks like test scores and grade point averages. Others think common sense, problem solving abilities and "street smarts" define intelligence. Standardized testing scores have proven unreliable and biased along racial and socioeconomic lines, and cramming for classes can lead to GPAs that aren't a true indicator of intelligence.
While we can't all agree on a standard for intelligence, we can agree that the human brain is the key to all of them. It has a great capacity to adapt, rewire and grow. Neural networks expand and strengthen through learning experiences. Stimuli make the brain stronger and more vital. This reinforcement of the brain's power affects intelligence across all standards, from street smarts to testing scores. Here are five ways you can increase your brain's capacity to take in and store new data. Or, said more simply, here's how you can get smarter.
