We identify three broad approaches - general public health messages, promotion by trusted politicians, and promotion by trusted nonpolitical influencers – identifying behavioral science relevant to each.
We highlight @deaneckles and colleagues’ research on how vaccine intentions can be increased (in the US and beyond) by informing people about the actually very high levels of vaccination+vaccine intentions in the general public.
High vaccination rate is key for herd immunity. But vaccine intentions are deeply polarized. ~40% of Republicans report they won’t vaccinate, essentially the same % as in Nov. A flat line for 5 months! (while other groups - e.g. racial minorities - have shifted substantially)
In pre-reg'ed experiment (N = 1,480), we varied whether Republicans saw endorsements of the vaccine from Republican politicians (including video from Trump’s CIPAC speech), from Democrats (including a speech by President Biden), or a neutral control.
