Would you drink water that had once been flushed down a toilet？ After it's been cleaned, that is. The climate is warming, and the population of drought-prone states California continues to grow. So recycling wastewater into drinking water may become a necessity.
But, it can be really hard for people to get over their disgust（恶心） at the thought of drinking recycled water. "People are grossed out by cycled water, because it was once wastewater-you know, the stuff that goes down your kitchen drains, your showers, your toilets. And even though it's cleaned up to a standard that is identical, if not better, than commercially bottled water, the key barrier to recycled water acceptance is people's disgust regarding it," said Daniel Harmon, a psychologist in University of California.
In one experiment, the researchers had some participants watch a short video promoting water conservation. And in another experiment, they added a video explaining why recycled water might trigger disgust even though all pollutants have been removed. And neither video had a strong effect on people's willingness to drink recycled water or to support the practice.
The messages were not enough to get them to actually use recycled water more. "Disgust is such a powerful reaction that simply giving more information is not going to really be effective." The study appears in the journal Basic and Applied Social Psychology.
Researchers say it's probably going to take a lot more to get people to embrace recycled water. For example, it might help to see members of their community drinking water that's gone, as it's called, from "toilet to tap," with no ill effects.
It is clear that these kinds of more direct campaigns for acceptance are necessary to get people to get over that psychological barrier-to take that first sip, so to speak. Cheers!
