Okay with that definition in mind, and the qualities of a “true skeptic” listed in that article as:

• Acceptance of doubt when neither assertion nor denial has been established
• No burden of proof to take an agnostic position
• Agreement that the corpus of established knowledge must be based on what is proved, but recognizing its incompleteness
• Even-handedness in requirement for proofs, whatever their implication
• Accepting that a failure of a proof in itself proves nothing
• Continuing examination of the results of experiments even when flaws are found

Those are the qualities of a scientist who has personal and intellectual integrity.
