BEATRICE: O, on my soul, my cousin is belied!
BENEDICK: Lady, were you her bedfellow last night?
BEATRICE: No, truly not; although, until last night, I have this twelvemonth been her bedfellow.
LEONATO: Confirm’d, confirm’d! O, that is stronger made which was before barr’d up with ribs of iron!
— William Shakespeare, Much Ado About Nothing, Act IV, Scene 1
The EPA opted to play politics with its final report on whether hydraulic fracturing (fracking) contaminates groundwater. Media have opted to go along. Some headlines:
- Reversing Course, E.P.A. Says Fracking Can Contaminate Drinking Water — The New York Times
- In U-turn, EPA says fracking can pose a threat to drinking water — Christian Science Monitor
- EPA reverses course on fracking safety — The Hill
So … the findings from 2015 have been erased? Something new suddenly bubble up? What?
Politics. The draft report stated that there was “no evidence that fracking systemically contaminates water.”
Environmentalists howled at it. Pressure was brought, letters were written, hands were wrung. (How strange that is, considering that because of fracking, we have seen actual, significant reduction in greenhouse gas emissions!)
So that sentence was struck from the report. In its place, the EPA report said the fracking process “can impact drinking water resources under some circumstances” that can “range in frequency and severity, depending on the combination of hydraulic fracturing water cycle activities and local- or regional-scale factors.”
Possibilities for which the EPA cites … no evidence:
However, significant data gaps and uncertainties in the available data prevented us from calculating or estimating the national frequency of impacts on drinking water resources from activities in the hydraulic fracturing water cycle.
It was simple rephrasing. Instead of saying there was “no evidence” that fracking contaminates water, it made it sound as if the reality of fracking contaminating water couldn’t be shown yet owing to “significant data gaps and uncertainties.”
Like Leonato, they jumped at lack of confirmation of the negative (Hero isn’t cheating on Claudio) as proof of the positive (Hero is “an approved wanton”). They were willing to believe that a lack of overturning the null, as opposed to outright confirmation of the hypothesis, was … confirmation of the hypothesis.
But it’s essentially the same finding as before.
Consider proving the existence of Bigfoot in the EPA manner. There’s no definitive proof there isn’t Bigfoot, based on the difficulty of conclusively proving a negative. But there’s no definitive proof that Bigfoot exists, which is the issue.
We could state the latter and be scientific about it. Or, to mollify Bigfoot enthusiasts, we could say there are significant data gaps and uncertainties in the available evidence for Bigfoot.
Stated that way, the argument is not inaccurate. But rhetorically it assumes Bigfoot exists although good evidence for him has yet to be found.
