I don't like objective truth as a concept, because it makes truth a matter of belief and easily turns into just another name for social truth. If you believe that something is objectively true but new evidence challenges that view, people will often ignore the evidence, because it goes against their established views.

Science, and research in general, should mostly be concerned with effective truth. The best objective-ish explanations so far, but something that can always be challenged with new evidence. The difference to objective/social concepts of truth is that you should always be willing to question the assumptions, beliefs, and reasoning ability you and people who agree with you have. If you discover something that goes against established beliefs, you should always start by assuming that you made a mistake somewhere. And if other people discover something like that, and it looks like they are seriously questioning the discovery, you should also take it seriously.
