yea the thing is its kind a waste of time and money for people to repeatedly perform the same badly controlled experiment over and over.
Sure, I agree with that. The next experiment should control for more variables. It's straightforward to improve upon the methods to leave less doubt. You can also do an experiment to show that some OTHER effect was likely responsible. Formulate another hypothesis that would explain Haggerty's data and test those ideas directly.
But if the people with the resources don't care about this particular issue, no one will do the experiment.
You can find out the same thing faster and cheaper if you just design it well to begin with.
I think if Haggerty had managed to get "no difference" among the three cages, no one would be calling for a better experiment, even though it would have been equally uncontrolled. We need to think about this.
Even if we ultimately prove that Haggerty's hypothesis is incorrect, she took a stab at addressing what she perceives as a gap or mistake in knowledge in the RIGHT way. There is no bad experiment as long as you are trying your best within your resources and acting ethically. There are unfortunate consequences of the media and concerned groups trumpeting EVERY paper as "the truth," but if that happens it is not really Haggerty's fault (IMO, after reading the paper.)
Haggerty did the right thing with her concerned skepticism. When was the last time you saw someone concerned about RF do something other than blog endlessly about RF sensitivity or spout mumbo-jumbo about the balances of life force?
Haggerty designed an experiment that controlled for a number of significant variables while changing the RF applied to the plants in a measured way. That's doing it right. Nothing is perfect. You can never control for ALL variables and there is always a need to minimize the impact of that. But you have to start somewhere, and if you have a fringe idea, that will probably be YOU in your own backyard.
Honestly, this takes the wind out of a lot of science **deniers'** sails. It's strong evidence against scientific conspiracy; evidence against "burying" of "weird" ideas. This person with no formal scientific credentials got a paper published that's based around a pretty deeply fringe idea. She deserved that publication on the basis of actually applying decent, if low budget science and getting a result.
I suspect that it won't be very long before there's a flurry of other careful experiments that explain Haggerty's results with a different interpretation of the causes. There will probably be theory papers on the spectral limits of the response of plants (as she cites some papers on outside-of-the-visible-light effects on plants).
It's not going to take that much time or that much money to refute this result, and in the meantime, Haggerty's publication suggests that properly executed scientific inquiry stands on its own, independent of preconcieved notions or weirdness of the result.
