#22 - Concept Reference, Strengthen

[lsat_yahya]

For those of you who may have accidentally selected (E), here is an explanation for why it is incorrect:

Essentially, it is saying: if you have groupthink, then you don't necessarily need voluntary deference. We know this to be false, as the text states that cohesion is necessary but not sufficient for groupthink. In other words:

GP --> cohesion

If we equate cohesion to voluntary deference, then:

GP --> voluntary deference.

Therefore, a study that tells us if you have groupthink, then you don't necessarily need voluntary deference would weaken the author's contention.

Hi lsat_yahya,

Good point overall. I'd like to note though that it's dangerous to treat voluntary deference as equivalent to cohesion. From the passage, we know it's something that happens in groups that are cohesive, but it's not all there is to group cohesion. The passage discusses many behaviors that happen in cohesive groups, from voluntary deference to illusions of invulnerability.

I do agree with you overall that answer choice (E) weakens this author's argument. Good work!
