Replication, Communication, and the Population Dynamics of Scientific Discovery
Fig 5
Differential power and replication dynamics.
Precision is indicated in blue, sensitivity in orange, and specificity in gray. (a) Low power initial studies (1 − β = 0.6, α = 0.2) but high power replications (1 − βR = 0.8, αR = 0.05). (b) High power initial studies (1 − β = 0.8, α = 0.05) but low power replications (1 − βR = 0.5, αR = 0.05). (c) and (d) as in (a) and (b), respectively, but only 10% of negative replications are communicated.
