My view is the opposite, basically the adage “measure twice, cut once.”
Work without research often is actively harmful in addition to failing and wasting time & resources. Research at least improves knowledge while not wasting other resources besides time.
However, I felt the context of this conversation was self-improvement though. In this particular context, it's easier to get things done without reading any motivational books/articles (in fact, most people get things done without reading about how to self motivate), and the contrary -- reading self-improvement articles -- doesn't mean anything if you don't do the actual work.
Let me quote the initial post of this subthread, which is the sentiment I agree with:
> "The thing about working on yourself is that it’s actually work. Reading an article, or a book on behaviour, self-improvement and what else doesn’t actually change you any more than reading Harry Potter does."
Work without reading about it: might work, and often does. Reading about it without doing the work: way less useful.
