| + | 63 | The reception figure above is a mean of self-reported submissions to PeptidePedia. It is '''weak evidence''' and is subject to three limitations that apply to every such figure on this wiki: | |
| + | 64 | ||
| + | 65 | * '''Self-selection.''' People who submit are not a sample of purchasers. Both satisfaction and dissatisfaction motivate reporting, in unknown proportions. | |
| + | 66 | * '''It measures reception, not quality.''' Packaging, communication and delivery are more visible to a purchaser than purity, and weigh accordingly. | |
| + | 67 | * '''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}} | |
