No, scientists accept new models only through a process of attribiton where the old believers die off and are replaced with the new believers.
"only" is a big word, kid. like all absolute qualifiers, it is one requiring but a single counterexample to refute.
I am not one of the big dogs on the history of science in the 20th century, so I cannot easily give you one clear example of a scientist accepting a new model after strongly supporting an old one. However: I know there have been not one but many such, and am quite certain one of the big dogs I have included as recipients of this note can easily provide names of such examples.
What I don't know is whether:
1. they will consider it worth doing, or
2. whether you are capable of accepting a factual rebuttal.
ant you meant "attrition" not "attribution" when you typed "attribiton", yes?
