Re: Are vulcans biologically smarter than humans?
Yes they stagnated. Once something had been determined, such as the impossibility of time travel, there was no reason to pursue ideas that contradicted what was known as fact. In ENT we see that they think exploration for the sake of seeing what is there is a poor use of time and resources. I think that may have been a cultural understanding that effected a lot of their development.
Wild ideas aren't logical.
They suck at being scientists
