I've been collecting EVP (Electronic Voice Phenomenon) recordings for about two years now, and I'm genuinely struggling with the problem of confirmation bias and pareidolia. When you're listening to white noise and static, your brain naturally tries to find patterns - words, voices, meaning. It's how we're wired.
So here's my question: how do other people approach this? Do you have specific criteria for what counts as a 'genuine' EVP? I've got hundreds of hours of recordings and maybe a dozen that could be interpreted as actual voices saying words, but I can never be 100% sure if I'm hearing what I want to hear.
The cleanest ones I've got are from investigations at Pendle Hill and an old mill in Yorkshire. In the Pendle recording, there's something that sounds like 'help me' or possibly 'hurt me' - hard to say. The mill recording is even vaguer, just sounds like someone's name being called, but it could easily be environmental noise.
How do other investigators handle this? Do you get colleagues to listen without context? Do you use software to filter or analyse? I'm trying to be rigorous here rather than just credulous.
