Name the source, or drop the number
Every statistic carries the study, the sample size and the year. Where a number turns out to be an article citing an article citing nothing, we say so in the post instead of repeating it. The widely-quoted “85% of callers will not leave a voicemail” figure is the clearest example — we went looking for the original study and could not find one, so it does not appear anywhere on this site.
