The quality or state of being endogenous; the degree to which something originates from internal rather than external sources.
From endogenic + -ity (suffix indicating a state or condition). This abstract noun allows scientists to measure or discuss how much a phenomenon depends on internal versus external factors.
Researchers studying disease use endogenicity to distinguish between sicknesses caused by your own body's dysfunction versus ones you catch from the outside—it's a crucial difference in medicine!
