The whole point of a TA is to bring traffic to your attention to help you visually find it before the possible RA.
Never maneuver in response to a TA, always follow the RA even if you have the traffic visual, but you should already be looking out for traffic even without a TA.
During a TA or RA the crew should be doing their best to visually locate the traffic. The idea that you would purposefully not look out is ridiculous at best and shows a complete lack of understanding of basic airmanship.
