The expression "lends credence to the conjecture" is standard. I was wondering if it sounds hyperformal or affected and can be replaced by "provides evidence as to the validity of the conjecture", "provides evidence for the validity of the conjecture", or "improves the confidence in the conjecture".

  • X lends credence to the conjecture = X supports the conjecture. A weaker assertion than validates, proves. Mar 20, 2019 at 13:55
  • Yes, but "provides evidence as to the validity" is definitely weaker than "validate" or "prove", as "evidence" implies some degree of uncertainty. Mar 20, 2019 at 18:09
  • You keep mentioning evidence (in principle, definitive confirmation of a hypothesis), but a relatively weak assertion about lending credence wouldn't usually be used in contexts where there's actual "evidence" involved. Even credence itself (weakly lent, more forcefully, conferred) is just about being "credible" (can't rule it out, not must believe it). Mar 20, 2019 at 18:29

Hyper formal or affected language is determined by your audience. Some groups won't mind "lends credence to the conjecture" others will be repelled by it.
