Google Flu Trends Was Wrong

March 21, 2013

Early this winter Google Flu Trends predicted that up to 11% of the US population would in have influenza by mid-January – the peak of the flu season.

The actual number was roughly 6% contracted influence during that peak period in January.

Why did Google Flu Trends get it so wrong?

Because Google algorithms looked at numbers only. Some researchers suggest that wide-spread media coverage inflated the flu searches by people who were actually not ill.

Looking only at numbers may produce patchy results. For a proper analysis you need context.

That’s why we started to integrate Squirro’s Context Intelligence engine into business intelligence systems such as Qlikview. Watch this short video for a preview of the Squirro-Qlikview integration.
