Chasing factoids

The Herald says

Almost four in 10 young UK adults describe themselves as digital addicts, according to research published by Foresters, the financial services company.

The story does quote an independent expert who is relatively unimpressed with the definition of ‘digital addict’, but it doesn’t answer the question ‘what sort of research?”

Via Google, I found a press release of a digital addiction survey promoted by Foresters. It’s not clear if the current story is based on a new press release from this survey or a new version of the survey, but the methodology is presumably similar.

So, what is the methodology?

Over 1,100 people across the UK responded to an online survey in November 2013 , conducted by Wriglesworth Research

There’s also a related press release from Wriglesworth, but without any more methodological detail. If I Google for “wriglesworth survey”, this is what comes up

wriglesworth

That is, the company is at least in the habit of conducting self-selected online polls, advertised on web forums and Twitter.

I tried, but I couldn’t find any evidence that the numbers in this online survey were worth the paper they aren’t written on.
