| + | 79 | === How this tally should be read === | |
| + | 80 | The reception figure above is a count of self-reported submissions to PeptidePedia, not a score: this wiki publishes none, and the figure says how many people wrote in rather than how good anything is. It is '''weak evidence''' and is subject to three limitations that apply to every such figure on this wiki: | |
| + | 81 | ||
| + | 82 | * '''Self-selection.''' People who submit are not a sample of purchasers. Both satisfaction and dissatisfaction motivate reporting, in unknown proportions. | |
| + | 83 | * '''It measures reception, not quality.''' Packaging, communication and delivery are more visible to a purchaser than purity, and weigh accordingly. | |
| + | 84 | * '''It is not comparable across communities.''' Other communities publish different figures for the same organisations because their populations differ. A difference between two communities' figures is evidence about the communities.{{r|tally}} | |
