I have similar problems about many scientists. I've been reading up on pervasive transcription and the potential number of genes for noncoding, functional, RNAs in the human genome. As far as I can tell, there are only a few hundred examples that have any supporting evidence. There are good scientific reasons to believe that most of the detected transcripts are junk RNA produced as the result of accidental, spurious, transcription.
There are about 20,000 protein-coding genes in the human genome. I think it's unlikely that there are more than a few thousand genes for functional RNAs for a total of less than 25,000 genes.
Here's one of the papers I found.
Guil, S. and Esteller, M. (2015) RNA–RNA interactions in gene regulation: the coding and noncoding players. Trends in Biochemical Sciences 40:248-256. [doi: 10.1016/j.tibs.2015.03.001]Trends in Biochemical Sciences is a good journal and this is a review of the field by supposed experts. The authors are from the Department of Physiological Sciences II at the University of Barcelona School of Medicine in Barcelona, Catalonia, Spain. The senior author, Manel Esteller, has a Wikipedia entry [Manel Esteller].
Here's the first paragraph of the introduction.
There are more genes encoding regulatory RNAs than encoding proteins. This evidence, obtained in recent years from the sum of numerous post-genomic deep-sequencing studies, give a good clue of the gigantic step we have taken from the years of the central dogma: one gene gives rise to one RNA to produce one protein.The first sentence is not true by any stretch of the imagination. The best that could be said is that there "may" be more genes for regulatory RNAs (> 20,000) but there's no strong consensus yet. Since the first sentence is an untruth, it follows that it is incorrect to say that the evidence supports such a claim.
It's also untrue to distort the real meaning of the Central Dogma of Molecular Biology, which never said that all genes have to encode proteins. The authors don't understand the history of their field in spite of the fact they are writing a review of that field.
Here's the problem. Are these scientists acting in good faith when they say such nonsense? Does acting in "good faith" require healthy criticism and critical thinking or is "honesty" the only criterion? The authors are clearly deluded about the controversy since they assume that it has been resolved in favor of their personal biases but they aren't lying. Can we distinguish between competent science and bad science based on such statements? Can we say that these scientists are incompetent or is that too harsh?
Furthermore, what ever happened to peer review? Isn't the system supposed to prevent such mistakes?
