how could two groups of 'experts' come up with such different conclusions, given they broadly agree of the evidence? David Aaronovitch in the Times identified the critical underlying issue behind the ensuing conflict: whether we take an individual- or a population-based approach. Essentially, the authors point out that any absolute risks are small from an individual perspective, and may generally be cancelled out by the enjoyment of eating, and the bother of changing habits. But these small benefits can be important from a public-health, population-wide perspective, since a lot of people making a small change, that only reduces their risk by a personally-negligible amount, can add up to thousands fewer cases of disease.
That's what has generated the disagreement. It can be perfectly reasonable for guidance to be given by authorities, and it can also be perfectly reasonable for individuals to ignore it. Both can be 'right'.
A piece I wrote on how psychology helps us understand fake news and information seeking.
Every day we face complex situations in which the information we need, and who we trust to provide that information, has a very real impact on our lives. How do we evaluate the competing claims of politicians on climate change policy, or Brexit; navigate medical information regarding vaccinating our children; or assess the relative merits of diet versus regular foods in adopting a healthy lifestyle?
Washington Post video discussing changes to Medicaid in the US. Republicans say they're not cutting Medicaid, they're increasing funding (just by less), others say this is a cut.
The White House includes misleading and incomplete information in its video explaining Obamacare's failures.
Many public conversations we have about science-related issues involve communicating risks: describing them, comparing them and trying to inspire action to avoid or mitigate them.
Just think about the ongoing stream of news and commentary on health, alternative energy, food security and climate change.
Good risk communication points out where we are doing hazardous things. It helps us better navigate crises. It also allows us to pre-empt and avoid danger and destruction.
But poor risk communication does the opposite. It creates confusion, helplessness and, worst of all, pushes us to actively work against each other even when it's against our best interests to do so.
So what's happening when risk communications go wrong?
