It seems to work a little differently to other clients by aggregating all the content on one relay first before sending it to the client, but I prefer this as it is faster and uses less bandwidth.
I think there can be different things going on under the hood.
Some people will be self aware, and not take arguments or positions too seriously - their own or others - they know they hold the points of view for group membership - they tend to not to like to debate them, aware of the futility.
More common though is ego-defense/group-defense reaction. This is the zealot. Both a person's ego (you're wrong) and their group (your group is wrong) is on the line. This is in addition to losing their membership of a group if they adopt a different position.
This was not such a problem when science was advancing slowly, but with acceleration of scientific development, this has become the retarding force. If we want to speed up science, we need to find a way of allowing truths to triumph faster.
One of the most disappointing things that I have learned is that most people hold opinions in order to be part of some group. If someone is a member of a group, it is almost not worth listening to their arguments, especially arguments in support of views held strongly by that group. They are arguing in order to maintain their group membership, not to find the truth. It appears this is true of academic and scientific disciplines as much as anywhere else.
It's vitally important to have a 2 second delay with closed captions. Without the delay you may start reading the dialog in advance, this degrades your enjoyment of the movie. Better to listen, and have the subtitles there as a backup 2 seconds later for anything you miss.
