Telepathy is doomed to skepticism, because it is not reliably reproducible, because its means of transmission is an imperfect vessel, the human mind.
They keep finding a small but statistically significant effect and even performing every possible means to tamper or bias proof the experiments, the effect remains. On top of that, there is absolutely no coherent scientific model to account for this so currently the most probable explanation is still that there is some unaccounted for environmental influence causing the effect.
It's frankly frustrating which is why I kind of fell out of interest in the entire field.
