Facebook won’t go as far as banning pages that spread anti-vaccine messages…[but] would make them harder to find. It will do this by reducing their ranking and not including them as recommendations or predictions inFirth. N. (2019). Facebook says it’s going to make it harder to access anti-vax misinformation. MIT Technology Review.
Of course this is a good thing, right? Facebook – already one of the most important ways that people get their information – is going to make it more difficult for readers to find information that opposes vaccination. With the recent outbreak of measles in the United States we need to do more to ensure that searches for “vaccination” don’t also surface results encouraging parents not to vaccinate their children.
But what happens when Facebook (or Google, or Microsoft, or Amazon) start making broader decisions about what information is credible, accurate or fake? That would actually be great if we could trust their algorithms. But trust requires that we’re allowed to see the algorithm (and also that we can understand it, which in most cases, we can’t). In this case, it’s a public health issue and most reasonable people would see that the decision is the “right” one. But when companies tweak their algorithms to privilege certain types of information over other types of information, then I think we need to be concerned. Today we agree with Facebook’s decision but how confident can we be that we’ll still agree tomorrow?
Also, vaccines are awesome.
