Do we have any evidence that the jury’s vote is not similarly biased? It may as well be.
Yep. Here is a literal study coming to exactly that conclusion: doi.org/10.4324/9781003188933-12
But also, you don’t really need a study for that. It’s pretty clear that people who just see songs and a recap and vote for what they have in their memory are more susceptible for it than a Jury that needs to literally rank every single song in a list from 1 to 25/26 in different categories.
And the image I posted above definitely shows how much running order impacts the televoting, as well as this image does (from when the running order was drawn at random):
I’m sorry, but I just disagree. With a relative of mine having studied musical theory for years, I definitely know that there is a huge difference between opinions of random people and people who literally have spent years with the theory and can judge the quality of singing and the challenges of a song in completely different and finer ways. There definitely is another level of appreciation.
