It is clearly political, but economics is inherently political - it justifies how society is organised. I would put it that someone having firm ideas of how an economy should be run doesn't in any way disqualify them from making a point and if an economist doesn't have firm opinions on how to organise an economy ... well, that would be fine, but surprising.
The abstract is putting forward a very important point in light of the environment that has developed where governments are expected to 'fix' the economy when a 'crisis' occurs. Both of those words are highly, highly political and also central to the practical branch of modern economics.
The core of this abstract is that there is evidence people have 'fine-tuned intuitions about chance, frequency, and framing' compared to what is currently believed by economists. If that is true, then that should have a bearing on the quantity and quality of regulation being recommended by economists.
