No, as scientific progress would be nonexistent. Science is based almost entirely on people standing up and saying "I believe you are incorrect, and I intend to prove it"; if we all agreed that the earth was flat, you'd be looking at pancake-shaped globes everywhere you went, because nobody would have had the presence of mind to say "bear with me, but I believe that idea may be mildly retarded". Sure, there's a lot of objectively stupid opinions in the world, and therefore a lot of baseless opposition to objectively good opinions and ideas, but the fact that we have such diversity allows us to have the range of good-to-bad in the first place; if we were all stuck in a monotone "mediocre", we wouldn't have any good ideas springing forth.
Let's suppose, for the sake of argument, that we were all unanimously agreed on objectively good ideas, instead of being locked into a psychological dead-end. We all agree that science is good, that knowledge is power, killing is wrong, selflessness is admirable, honesty is golden, and sentimentality is never an excuse to hold up progress. What then? Call me crazy, but I still believe we wouldn't go anywhere, for the same reasons I previously went over. The evolution of a species is caused by favorable mutations replacing less-useful traits with superior ones, and in a world without such mutations, we'd all be single-celled organisms. The same principle applies to academia, as our pool of knowledge cannot be expanded without being able to tell right from wrong. Nowadays, it's common sense that an attempt to cure a fever by using leeches to remove a witch from an afflicted person's stomach is, y'know, fucking stupid, but there was a time where everybody was on board with that because that's the best we could do; if nobody between then and now said "that's fucking stupid" and set to work on research for cures that didn't make the affliction worse, you'd have a faceful of parasites every time you developed a sneeze. Even if we could all adjust our beliefs unanimously to accept a new piece of information, we'd be waiting for that information to fall out of the sky, because vast amounts of research and inquiry are primarily inspired by dissent.
Outliers for the win.
