Almost everyone wants to get smarter. We struggle to improve our 36_ , intelligence and attention. We drink cup after cup of coffee to help us 37_ the day.
38 , a new study published in Current Directions in Psychological Science warns that there are 39 to how smart humans can get.
Each of our body parts develops in a certain way for a reason. 40 _, we are not 3 meters tall 41 _ most people’s hearts are not strong enough to send 42 _ up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of 43 , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more 44 during childbirth.
The study of Jews, who have an average IQ much _ 45_ than other Europeans, showed they were more _46_ to develop diseases of the _47_ system. This might be because of their increased brainpower.
If intelligence cannot be improved, can we at least get better at _ 48 _ ? Not really, say scientists. They studied _49_ like caffeine (咖啡因)that improve attention. They found the drugs only helped people with serious 50 _ problems. For those who did not have trouble paying attention, the drugs could have the 51 _ effect. Scientists say that this suggests there is a(n) 52 limit to how much people can or should concentrate.
Our memory is also a “double-edged sword”. People with extremely good memories could 53 having a difficult life because they cannot _54 bad things that happen to them.
Thomas Hills, one of the authors of the paper, said that 55 all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.
