In the comments on this question, there were a two opposing opinions (anti, pro) on the technique of revealing slides bit-by-bit, rather than all at once. The argument against doing so was that revealing slides bit-by-bit is "micromanaging" viewers' attention and that some people prefer to have access to all of the information on the slide before starting to process it. The argument in favor was that revealing a whole slide at once gives too much information, making the talk difficult to follow.
What are the pros and cons of these two approaches? How should I choose which one to use? Are there recommendations from authoritative sources and/or supported by reliable evidence? I'm mainly interested in technical presentations in science or mathematics, including both lectures to students and research talks to peers. There may also be diversity issues (dyslexia, ASD, etc.) that are relevant.
I think this question may be closely linked with the issue of how much information to put on each slide. If you have a slide that just consists of a few short bullet points, then I agree that there's not much point in revealing them one by one. But for technical presentations, one often has slides that have more information than one can reasonably take in at once.
This was one of several questions asked here but none of the answers there seems to address this particular question.
\pausein Beamer. I try to break slides up where natural breaks in thought are or before something potentially confusing or abstract to give the reader a momentary break to collect their thoughts. Here's an example of a talk I gave a couple years ago: fields.utoronto.ca/talk-media/1/25/93/slides.pdf . This was a short talk, so it's a bit more jumpy than the way I do classroom notes, but it's not too far off.
