Most of them lag the release by a similar amount, which you'd expect since the trend of giving kids smart phones didn't start the moment the iPhone came out (would have seemed insane at the time, in fact).
[EDIT] thought the sleep one especially is weird. WTF happened in the 90s to make sleep get so much worse?!
- zzalpha 9y agoMost of them lag the release by a similar amount I interpret them slightly differently. IMO, most seem to show a preceding trend followed by trailing acceleration. One (I believe it was the Teen Sex graph) shows a steady trendline with no point-in-time correlation whatsoever. You could put a line almost anywhere on those graphs labelled "iPhone" and it'd be about as compelling. Take the line out and I absolutely agree that something that was going on for at least a decade prior to about 2010 seems to have sped up. But the iPhone line feels entirely artificial and, IMO, undermines the impact of those visuals.
- orbitur 9y ago> WTF happened in the 90s Personal experience as a child of the 90s: for the middle class family, a TV began to occupy the bedrooms of teens. They were still too expensive in the 80s to justify, and cable wasn't nearly as pervasive in the 80s.
