Do you prefer to negate a positive function or write a negative one?

Example
!IsValid() vs IsInvalid()

undefined

    That would depend on the original field i use. If the field first expected to be told something is invalid then ill use IsInvalid()

    Though often i use negate positive since saying 'not InValid' feels clunky

    This might be a question for the philosophers, but I also prefer leaving the 'not' to the logical operator by default to avoid double negatives when reading.

    IsValid, but we can do better! Validate on rulesets to avoid many if blocks for validation checking is far clearer IMHO. 😉
