That's tied in with the need to be succinct. Expressing uncertainty often adds verbosity and cognitive load onto the reader. Often it also adds redundancy, given that uncertainty should be taken for granted in certain contexts. Note that in these last two sentences, the word "often" added verbosity, which is an example of what I am talking about. If someone is just expressing their opinion, I don't like to read a bunch of hedging. I get that you are uncertain and this is just your opinion, stop telling me that over and over and over. I wish there was a new shorthand/syntax/convention/notation for expressing uncertainty. All statements are delivered succinctly, with some notation for saying I am only 70% certain, perhaps by putting 0.7 as small superscript text.
