"lends credence to...' [closed]

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".

Solution 1:

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.
