Yes, absolutely.
There are well-established standards, if you want, in terms of the quality of the science and the strength of the evidence. Of course, ideally, we would like to have the same findings being reproduced by others, being peer-reviewed, but under difficult circumstances and with lots of uncertainties, people can determine whether the available science, the available evidence, is of sufficient quality to be incorporated into decision-making. In the case that it's not, and there is a void in the evidence anyway, it's then up to the policy-makers, of course, to take the relevant course of action.
