Not in archaeology but appropriately in Critical Thinking and Ethical Reasoning!
One wonders how many archaeologists would pass? All of them we suspect, providing their answers were kept confidential! Anyway, since we designed the Counter we thought we’d answer the question.
Q: How useful is the Erosion Counter as evidence of the Activities of metal detectorists?
A: It’s the very best guide there is. It must be, as it’s based on and confirmed by every one of the studies that have been carried out – by archaeologists, resource guardians and detectorists themselves. It has never been challenged by academics, quite the reverse, and the only opposition to it has been blanket denial (and abuse, and threats) by those with a vested interest in it being wrong. Its core conclusion, that 70% of detectorists don’t report all their recordable finds has recently been confirmed by the Portable Antiquities Scheme.
So in summary, the application of critical thinking and ethical reasoning leads us to conclude that the Counter is extremely useful as evidence of the activities of at least 70% of metal detectorists.
