With current complex data processing pipelines it is almost trivial to add e.g. a wrong sign to some variable to get "results" from data that doesn't contain any. I've had many "results" disappear after I found a bug. I could have probably gotten papers quite easily by ignoring the bug. I'm quite certain a huge share of "results" are due to bugs. Probably many of my own too even though I stress about this constantly. An intentional bug would be practically impossible to show to be intentional. With notebook/REPL style analysis there wouldn't necessarily even be any documentation of the bug. I'd wager it actually happens, and even surprisingly often. We only know of fabricators who are bad at fabrication.
