Hey I answered D too, but after reviewing the passage I found that there were a few problems with it that (I think) make it a wrong answer choice:

(1) the claim made in lines 45-48 that you quoted above is very specifically what "researchers have identified" and not necessarily what the author thinks

(2) it is plausible that outside information CAN influence group decisions even after they have become determined by groupthink i.e. the group decides (via group think) that they should cross the bridge, but subsequently is given new (outside) information (perhaps a blueprint that shows that the bridge is unstable) that changes their final decision - in this case it would seem that the outside information did influence the group decision

Hey Alan,

I just tried again and it's still not loading up on my end. Any suggestions for what I should be doing different? I've cleared my history and cache, but that doesn't seem to be helping anything.

I was confused with the same question and explanation provided, I ultimately discarded answer choice A just based on the fact that they used the word "discover". The passage specifically cites "mistrust of uncertainty" and I think "uncertainty" is not affected by lack of "discovery"...

Thanks for the tips, but I restarted my computer and am using safari... the page takes me to the syllabus now but the video explanations do not have sound (and my sound is definitely on and working for all other sites)
