To clarify. The bullet points are listed under "Marks of Good Science". Holding a degree does not mean your publications or claims are good science. It's fine if Ted wants to only have degree holders as speakers, but they should be clear that it's a bias they've chosen, not "good science".
They're organizers of a conference, not academics. If you require them to replicate the experiment to prove it's good science, you're crippling them. It's perfectly appropriate for them to apply conservative heuristics to make their editorial load manageable, and a good heuristic is "has the appropriate academic credentials."
