The present paper discusses the claim that value-free science is impossible. After applauding the observation of Colombo et al. Review of Philosophy and Psychology 7: 743–763, (2016) that this is at least to a considerable extent a psychological question, and should therefore be studied using the methods of psychological science, the studies performed by these authors were examined and unfortunately found seriously wanting in various respects. Beyond the merits or demerits of that particular piece of work, the discussion lead to a conclusion likely relevant to the entire discussion about the alleged impossibility of value-free science: Showing the impossibility of value-free science would entail at least a) defining what the term science is intended to cover, b) providing high level evidence that few if any scientists in the relevant area(s) are immune to non-epistemic influences (else one could presumably achieve value-free science by having scientific hypothesis only evaluated by those who are immune), c) that these influences meaningfully bias the results of science, d) that there is no way to correct for these influences, and e) explain why – unlike epistemic appraisal in science – the epistemic appraisal of this argument can be trusted.
