Totally anecdotal but I think phones have made us less present, or said another way, less capable of using our brains effectively. It isn't exactly dumb but it feels very close.
I definitely think we are smarter if you are using IQ, but are we less reactive and less tribal? I'm not so sure.
"Although the longitudinal sample was small, we observed an important effect of GPS use over time, whereby greater GPS use since initial testing was associated with a steeper decline in hippocampal-dependent spatial memory. Importantly, we found that those who used GPS more did not do so because they felt they had a poor sense of direction, suggesting that extensive GPS use led to a decline in spatial memory rather than the other way around."
