 So maybe our doctors won’t take the data shared by others at face value. Suppose instead they discount it, especially when the source’s viewpoint differs greatly from their own. O’Connor &amp; Weatherall (2018) and Weatherall &amp; O’Connor (forthcoming) explore this possibility, and find that it can lead to polarization. Instead of the community reaching a consensus, some doctors in the community may abandon the new treatment, even while others conclude that it’s superior.
