If I were asked, I'd frame the question somewhat differently. I would ask whether we are finding that practitioners of science, many of whom have forfeited any ground for thinking that there really is objective right and a wrong, are simply acting more consistently with their metaphysical amoralism.
When scientists one after another deny the existence of any transcendent basis for moral behavior, when they embrace a metaphysical naturalism that entails an amoralist view of the world, then why should we expect that they would hold themselves to arbitrary standards of conduct if violating those standards is in their self-interest?
Lest you think that I'm overstating the degree to which science (and philosophy) has abandoned such a basis let me offer just a few of the many quotes on the subject that could be adduced:
"What’s to prevent us from saying Hitler was right? I mean, that is a genuinely difficult question." Richard DawkinsWhen people come to think this way it's just a short step to rationalizing otherwise unethical behavior if that behavior helps one gain tenure, grants, and prestige. In other words, scientific malfeasance is consistent with the naturalistic materialism held by many scientists. It's inconsistent only with the worldview of those scientists who've not succumbed to the modern infatuation with naturalism.
"[I had] been laboring under an unexamined assumption, namely that there is such a thing as right and wrong. I now believe there isn’t…The long and short of it is that I became convinced that atheism implies amorality; and since I am an atheist, I must therefore embrace amorality…I experienced my shocking epiphany that religious fundamentalists are correct; without God there is no morality. But they are incorrect, I still believe, about there being a God. Hence, I believe, there is no morality....Even though words like “sinful” and “evil” come naturally to the tongue as, say, a description of child molesting. They do not describe any actual properties of anything. There are no literal sins in the world because there is no literal God…nothing is literally right or wrong because there is no Morality.” Philosopher Joel Marks, An Amoral Manifesto
"For the secular man there's no answer to the question, why not be cruel." Philosopher Richard Rorty.
"Truth (including moral truth) is whatever your peer group will let you get away with saying." Philosopher Richard Rorty
"One who does not believe in God or an afterlife can have for his rule of life…only to follow those impulses and instincts which are the strongest or which seem to him the best." Charles Darwin (Autobiography)
"Ethics is just an illusion fobbed off on us by our genes to get us to cooperate." Biologist E. O. Wilson and Philosopher Michael Ruse
"Let me summarize my views on what modern evolutionary biology tells us loud and clear – and these are basically Darwin’s views. There are no gods, no purposes, and no goal-directed forces of any kind. There is no life after death....There is no ultimate foundation for ethics, no ultimate meaning in life, and no free will...." Biologist Will Provine
“[T]he worldview of science is rather chilling. Not only do we not find any point to life laid out for us in nature, no objective basis for our moral principles, no correspondence between what we think is the moral law and the laws of nature, of the sort imagined by philosophers from Anaximander and Plato to Emerson. We even learn that the emotions that we most treasure, our love for our wives and husbands and children, are made possible by chemical processes in our brains that are what they are as a result of natural selection acting on chance mutations over millions of years. And yet we must not sink into nihilism or stifle our emotions. At our best we live on a knife-edge, between wishful thinking on one hand and, on the other, despair.” Nobel laureate physicist Steven Weinberg
