Android isn’t cool with teenagers, and that’s a big problem::Nearly 9 in 10 US teenagers use an iPhone, spelling disaster for Google’s mobile future
“Nearly 9 in 10 US teenagers use an iPhone”
No.
“Nearly 9 in 10 US teenagers SAY THEY use an iPhone”
FTFY.
How many actually use an iPhone remains to be seen.
You have literally described all surveys, good job.
It isn’t like people who run surveys don’t know this and take it into account, there has been plenty of math that has been sussed out to try to remove the kind of bias that can happen in self reporting.
There’s reams of science dedicated to this problem, it isn’t new. I’m tired of seeing this argument shat out without a shred of consideration for scientific and mathematic history of taking surveys.
