Although I work from a much smaller store of knowledge and experience I suspect there is another factor beyond lack of interest. The 'fear of contagion' caused by the possibility od seeing something that cannot easily be explained away.
Is this something you have any evidence for? My experience is that all (good) scientists are very excited to find anomalous things that cannot be explained away. It is what they live for. I have never heard of this fear of contagion nor seen it prevent other anomalies from being of interest.
A good example would be the US guy who has now (twice) with different materials claimed much higher temperature superconductivity than anyone else has found. Both times there have been problems with replicability. The first time there was a problem with identified poor methodology. But lots of people are interested.
However, equally, good scientists will be skeptical and rigorous in their evaluation of evidence.
Here is an example
and here is a very fast (negative) replication:
the (scientific) jury is still out on this one but it looks more likely that this was a mistake.
But even though there is as yet (and maybe never will be) no cheering I do not see fear of contagion.
Merely considerable interest tempered by the likelihood this is not what it is claimed to be.
