Years ago, science discovered a cure for polio, antibiotics, electricity and nuclear energy. They did this through rigorous lab work, experimentation and the scientific method.
Today, “scientists” google pictures and make arbitrary decisions about what the pictures portray.
Apparently, that’s now what passes for “science”.
And the conclusion?
“It is clearly better from the dog’s point of view if you express your fondness for your pet with a pat, a kind word, and maybe a treat.”
Wow. That’s deep. It’s a good thing I had a “scientist” to tell me that or I would have never figured it out.
