Used as an argument, I think you'll find believers will have responses for it. Such as:
- The healthcare system is evil and wants to keep you sick to make more profits.
- Same with the oil industry, etc.
- It's based on spiritual principles, so science and unbelievers can't harness it.
- Industry is too ignorant/close-minded/controlled/etc to think outside its box.
- Powerful people do use it, but use their power to keep it secret.
- Its a conspiracy. Proof = you don't know its a conspiracy.
And so on.
The comic is great, but I do have one nitpick... it's a bit of a strawperson in two ways.
1) Many of these blank checkboxes should actually have checks in them.
It's a skeptic's personal nightmare that businesses really do pay consultants to do this crap and so many are convinced there's a business case.
Health insurance companies cover naturopathy, chiropractic, homeopathy; corporate HR departments employ graphologists, lie detectors, and even mediums to screen job applicants; mineral exploration and landscapers employ dowsers; stock brokers consult astrologers and fung shui experts.
2) For the most part, paranormal claimants had already moved past the efficacy argument in the 19th century and watered down their claims appropriately.
Specifically, the defenders are pretty consistent in that they're claiming these abilities 'exist' but are 'unpredictable and unreliable, and cannot be deployed on demand'
How this is different from my description as 'useless and indistinguishable from ordinary guessing' is a distinction without a difference to them.
Another defense is that these abilities are undeveloped. ie: they are an emerging field, rather than a mature field like geology or physics. They argue that we are building a circular argument: that we are rejecting calls to invest in their development on the grounds that these technologies are underdeveloped.
As it happens, the best counter to this is that there *has* been investment in their development, and it has not borne fruit. We can thank Martin Gardner for documenting the Soviet military's huge investment in resources exploring paranormal abilty weaponization. Also Jon Ronson's exposee of the US Army's attempts, which was also turned into a movie.
