You underestimate the value of surprising and unexpected results for one's academic career.
Validation is everything.
Validation rarely happens nowadays for many many results.
In biology, if you don't have validation you aren't getting published in Nature. Maybe other fields play faster and looser, but this field demands evidence for claims and support from other sources validating these findings before they are seriously accepted by the community.
How is the validation done?
If you discover a brand new biological phenomenon, are you saying you can get it published unless someone else does the same experiment and gets the same result?
