r/FringeTheory↗

Fringe Theory: the place for fringe theories and all things related.

r/FringeTheory is not about believing fringe ideas. It’s about subjecting every idea—mainstream or fringe—to the same epistemological standard. FringeTheory isn’t defined by its conclusions, but by its method. Every claim—mainstream or fringe—is expected to meet the same epistemological standard. Before asking what is true, ask how we know.
