Columnist: Neuroscientists have found that states of profound creativity are accompanied by an increase of theta brain waves, which occur in many regions of the brain, including the hippocampus. They also found that listening to music increases theta waves dramatically. Thus, one can attain a state of profound creativity merely by listening to a tape of recorded music.
The columnist’s reasoning is most vulnerable to criticism on the grounds that it
(A) takes for granted that there is a causal connection between the hippocampus and being in a state of profound creativity
(B) fails to consider that music is not necessary for one to be in a state of profound creativity
(C) does not rule out the possibility that listening to music by means other than a tape recording also increases theta waves
(D) ignores the possibility that an increase in theta waves may not always be accompanied by a state of profound creativity
(E) provides insufficient reasons to believe that people who are not in states of profound creativity have low levels of theta brain waves
EXPLANATION FROM Fox LSAT
No, this is stupid. The logic here is just like saying, “Scientists have discovered that law professors talk a lot. They have also found that drinking an entire bottle of Jack Daniels causes people to talk a lot. Therefore one can become a law professor by drinking a bottle of Jack Daniels.”
The problem here is 1) correlation doesn’t equal causation and 2) the argument is confusing cause with effect. Just because creativity is correlated with theta brain waves doesn’t mean that one causes the other. And furthermore, it certainly doesn’t mean that theta brain waves cause creativity. It could be that creativity causes theta brain waves.
We’re asked to find grounds for finding the columnist’s reasoning vulnerable. I think we’ve already done that.
A) If this said “theta brain waves” instead of “hippocampus” I’d like it. As is, it feels like a trap, since the hippocampus is only one region where theta brain waves occur. This just doesn’t seem to be an accurate description of what the argument was actually saying.
B) No, the argument says that music is
sufficient for creativity, not that it’s necessary.
C) What? This is beside the point. It’s possible that the columnist would say that listening to live music
also causes creativity, and that wouldn’t ruin the columnist’s argument. No way.
D) Right. This is a better version of A. The columnist has assumed that theta brain waves
cause creativity. If D is true, then the columnist is shown to be a moron.
E) The argument doesn’t even mention people who are
not in states of creativity, or who have
low levels of brain waves. This is just plain irrelevant.
Our answer is D.
