Equation 15 · Part 1 · The Bandwidth of Culture: Transmission Fidelity to 2100

Symbol rho_h

ρh\rho_h
ρh\rho_h

What this part means

ordinary human-to-human transmission fidelity.

Its job in the formula

rhoho_h is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

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

The passage around this formula

where ρh\rho_h is ordinary human-to-human transmission fidelity, ρm\rho_m is the fidelity of a machine-mediated re-emission — empirically lower per the tail-collapse result above — and sts_t is the share of newly circulating content, at time t , that is machine-generated rather than human-originated. This decomposition does one useful piece of work: it turns “will culture’s transmission fidelity fall this century” into the answerable, if still hard, empirical question of how sts_t moves, and it is that question the scenarios below are actually scenarios about.
