Death threats are being made against climate scientists , and doctors and mothers who vaccinate . In addition to widespread spreading of diseases such as measles and HPV through vaccination hesitancy [5-8], distrust of established scientific treatments for cancer are leading patients to adopt dangerous substitute measures . More generally, the number of countries with disinformation campaigns is reported to have more than doubled to 70 in the last two years, with Facebook remaining the top platform for those campaigns .

However, DiResta and others have pointed out that what is missing is a big picture understanding in the national and global populations involving millions of people  while Starbird has also highlighted the need to understand the important role of unwitting crowds [16,17]. Indeed, the impact of crowds -- and in particular undecideds -- is known to play a central role in the dynamics of other societal systems such as financial markets  and elections [1,2,18].
