Groundbreaking science is done at the edges of knowledge. Typically the first reports of new phenomena are rather sketchy and not very convincing. What happens is either 1) people can't replicate the results or find a way to explain the results in a more conventional way or 2) Later results support the initial findings and the original discoverer is hailed as a visionary, maybe even winning a Nobel for it. But the first case is far, far more common than the second, so it makes sense for scientists to be very skeptical of new findings.
