Nature: Do disruptive climate protests work? Real-time survey finally offers answers

Support for a moderate environmental group rose after a motorway closure, substantiating the ‘radical flank effect’.

Although the article claims that gain in support, it notes that "the researchers did not find a statistically significant effect on support for climate-friendly proposals", and that other looks at the effects of disruptive protests have found negative effects.

So I guess the point is that if you position your environmental group well, you can take advantage of the protests of more radical behavior.
