Equation 14 · Part 2 · The Bandwidth of Culture: Transmission Fidelity to 2100

Symbol rho_h

\rho_t = \rho_h + (\rho_m - \rho_h)\, s_t, \qquad \rho_m < \rho_h

\rho_h

What this part means

ordinary human-to-human transmission fidelity.

Its job in the formula

rh $o_h$ is one of the signed contributions combined to compute the quantity on the left.

Where the article explains it

where $\rho_h$ is ordinary human-to-human transmission fidelity, $\rho_m$ is the fidelity of a machine-mediated re-emission — empirically lower per the tail-collapse result above — and $s_t$ is the share of newly circulating content, at time t , that is machine-generated rather than human-originated.

The passage around this formula

…a human transmission chain. The mechanism Shumailov and colleagues describe operates by pulling $\rho_t$ itself down as the share of machine-mediated content in what gets re-ingested rises: $\rho_t = \rho_h + (\rho_m - \rho_h)\, s_t, \qquad \rho_m < \rho_h$ . where $\rho_h$ is ordinary human-to-human transmission fidelity, $\rho_m$ is the fidelity of a machine-mediated re-emission — empirically lower per the tail-collapse result above — and $s_t$ is the share of newly circulating content, at time t , that is machine-generated rather than human-originated.
