They should follow it up with work on the effect of presenting scientific findings through the medium of a video which continually shifts from one person's speech to another, with each speaker rarely allowed more than one sentence before the voiceover or another speaker continues the thread of their message, or some floating text is slowly revealed as it drifts across the screen.
It's probably received wisdom that floating images, continual movement on the screen, and cutting between different presenters holds the attention of an audience, but there's a clear difference between getting eyes-on-screen-for-as-long-as-possible, and communicating a moderately sophisticated message.
Maybe I'm too old for this shit.
