That's a very interesting video, thanks for sharing
His main conclusion the way I get it is: (provided people see what's popular with others while doing their rankings), good entries will generally be rewarded (a little), however the big frontrunners will be mostly determined by the initial hype that gains steam and then blows up out of proportions. Who gets the initial hype is up to fate / people who are the first to express their hype.
However, to which extent are his experimental conditions applicable to the ones of Eurovision?
In theory, the juries vote independently, and the public doesn't know anything about the actual results while taking the vote. So, if there is any hype, it doesn't happen as directly as in the video's experiment where people can immediately see how others have voted.
The "indirect hype" imo includes odds, views on youtube/replays on spotify, and fan rankings like the eurovision scoreboard app. It is, however, mostly pre-contest hype that does not directly reach everyone.
As for the televotes, how many of the people voting are actually aware of all these things? And how big percentage of the final televote do they make? My opinion is:
very little, it's just the fandom that likes to overestimate its own importance. 80%+ of the people voting only get influenced by the people they watch the show with, but they know nothing about hype whatsoever. They don't really bother checking who's the odds favourite or whom are the wiwi's getting crazy about on this particular night. In other words, the televote is much closer to the independently voting pool from the experiment.
I see the juries, on the other hand, as much more likely to be influenced. Firstly, we know the theory of them not talking to each other about their rankings is not always respected. Also, they probably don't care much about fan polls either, but since they have to be invested in the contest for a longer period of time than the average televoter, I'd be very surprised if some of them didn't check the odds at the very least. Also, the overall effect of a hype influenced jurymember is much higher, because you only need to influence one person to somehow influence one fifth of that country's jurypoints (and that single person also impacts rankings of every contestant, while a single televoter doesn't).
So, if there is some hype effect applicable to Eurovision, I'd say it is much more likely to help anyone (in this case,
) with the juries.
