Risk assessment precautionary activities

Instead of assessing risk, I suggest that we should try to assess riskiness in the everyday sense of this term, where it refers to the epistemic possibility of harm, not merely probabilities of identified types of harm. Whereas risk relates to outcomes, riskiness is a property of a thing, situation or activity and is relative to our knowledge about it. I suggest that what are normally termed precautionary approaches are concerned with riskiness, rather than just risk they are concerned with whether, for all we know, there is a possibility of harm, not just with the probabilities of known, specifiable types of harm.
