Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Scientific and forensic evidence refutes the possibility of spontaneous human combustion, demonstrating that extreme thermal destruction of bodies always results from an external ignition source combined with bodily fat acting as a fuel and clothing acting as a wick.

The analysis

The claim is specific and falsifiable, so it passes Step 0. The retrieved literature unanimously rejects the literal interpretation of spontaneous human combustion (SHC). Instead, forensic investigations attribute these rare and dramatic burning events to the 'wick effect,' where an external ignition source lights clothing or other materials, allowing human fat to sustain a slow burn. Papers [1], [2], and [3] all highlight the necessity of an external heat source and rule out true spontaneity. Therefore, the evidence clearly refutes the claim.

Paper [2] explicitly states that spontaneous human combustion has no scientific background, explaining extreme body destruction instead through the 'wick effect' involving external ignition, molten fat, and clothing.

Paper [3] examines cases of isolated body combustion and emphasizes that external heat sources are always found near the body, debunking the notion of truly spontaneous ignition.
