We dont see things as they are, we see them as we are.
If you have inherent biases, you can swing anything in your favour. Which is what they have done in this study. "We dont like escorting so lets publish the "facts" to suit us."
As Einstein said, when the facts dont fit the theory, change the facts.
Colleges are a cesspit these days as well. So inherently biased to suit their own agendas. Wasnt there a lecturer in ireland who said the whole pandemic was a hoax.
Once you have inherent biases, you are going to frame the "facts" to suit your bias.
