Why do most papers in CS conferences say "novel" repeatedly now a days?

I find this extremely irritating.

It is up to me, as the reader, to judge whether this is novel or not.

Please tell me what you have done, rather than telling me that (you think) it is novel.

Don't tell me that your results are important, or surprising, or anything like that. I will judge the importance or surprise or novelty.

It is not like if you didn't tell me it is important (if indeed it is) I wouldn't notice.

And if it is not novel, why would you be submitting it to the conference, anyway?

@MartinEscardo I don't really agree. I think understanding why authors think their work is important is good information to have. As a reader I am happy to read this opinion, then agree, disagree, or reserve judgement as I see fit. Claims of novelty are to help the reader differentiate quickly what in the paper was already known from what the author believes is new. These sorts of claims are helpful to reviewers but even more helpful to non-expert readers (sometimes the same thing!)

@RanaldClouston

The point is that you won't convince me that your work is important if you say it is important. You need to say something else to convince me it is important.

@MartinEscardo do people really claim their work is important without giving reasons?
@RanaldClouston @MartinEscardo Yes. Politicians say they "refute" propositions without giving disproofs. Academia is full of politicians.
@RanaldClouston The reasons alone should be enough!
