Have you looked into what the service comprises, though? It's, iirc, $50 per 20 minutes of full attention, one-on-one talk, or something along those lines.
If you pay dearly for just a few minutes, you wont wax philosophical over your megalomania, or go on a persecutory complex rant, or throw around buzzwords you don't understand.
This forces the crank to re-evaluate what they have created, what they want to ask, what they really know, what is the gap in the knowledge they're trying to bridge, and whether the whole endeavour is really worth it. All before they even actually talk to the physicist.
Admittedly, my working definition of 'better outreach' in this case is 'successful in discouraging people from becoming crackpots'. So this is seldom about really teaching the science to the public, as it is about pruning the false impressions of what the science is, so that they don't macerate and spread as readily.
Yes, and the cost will help weed out some of the lazier trolls -- although, as the comments on her blog post announcing the service illustrate, some of them will just find the nearest free soapbox and whine about it.
My worry from an anti-crackpot standpoint is more one of triage, though. To be sure, some people will be spurred by the cost to rationally examine their theory and recognize it as aphysical, and maybe they need to be induced to do that in this way. But there are also people who arrive at unscientific ends by unscientific means, and I suspect their internal vetting process is to ask themselves whether they still think they are very smart and therefore everything they believe is true -- and then to also not bother actually talking to a physicist, more convinced they're right and more entrenched in their wrongness than ever. So now we have to ask whether those who are wrong for the right reasons and may be helped along will outnumber those who are wrong for the wrong reasons and will only be emboldened.
I think the latter are more common largely because modern American conspiracy theories and related follies are thick with them. At the root of Hammonism is the idea that Ken Ham thinks antediluvians fed Christians to dinosaurs before Noah built a floating wave-powered flush toilet and he's real smart so you should too. The Hovind Theory is little more than an excuse for Kent Hovind to pretend he has a real doctorate. Flat Earthers all cluster around their favored purveyor of well-gee-sure-looks-flat-to-me zetetic nonsense and rant about how everyone else is a CIA plant. Timecube was, by word count, mostly rants about how everyone but Gene Ray was educated stupid. Even the Dean Drive and the polywell fusor have little cults around them, and mewing runs mostly on the story that the Mews are persecuted orthodontic geniuses rather than dangerous crackpots. On the low end of the spectrum, conspiracy theorist Youtube is rife with these sorts of personal blogs about how persecuted they are by being asked to substantiate their nonsense, and the forum equivalent is about as rampant. I don't do social media, but what other people have shown me is along the same lines: as conspiracy theorists develop, they approach 100% conspiracy and 0% theory, because the point is to feel like they know something despite all evidence to the contrary.
This service is tantamount to an offer to put up or shut up. Some of them will try to do the former and realize they should really do the latter, sure, but we already select against crackpots willing and able to do either. The majority of loons who last long enough to spread their nonsense have already developed a defense mechanism against ever having to do either, so all this will do is motivate them to get out ahead of it.
If you want to prune false understandings of what science is, I think engaging with their purveyors is already taking the wrong tack. Detailed explanations of how bad science is bad are boring. Inviting people to come point and laugh at these stupid assholes who believe wrong things and are bad is sinking to their level, yes, but that's the level on which all of society operates now anyway, and it does have the advantage of being more engaging.
