Pre-Checked Cookie Consent Invalid, EU Court Rules
The study, which looked at how consumers interact with different designs of cookie pop-ups and how various design choices can nudge and influence people’s privacy choices, also suggests consumers are suffering a degree of confusion about how cookies function, as well as being generally mistrustful of the term ‘cookie’ itself. (With such baked in tricks, who can blame them?).
The researchers conclude that if consent to drop cookies was being collected in a way that’s compliant with the EU’s existing privacy laws only a tiny fraction of consumers would agree to be tracked.
The paper, which we’ve reviewed in draft ahead of publication, is co-authored by academics at Ruhr-University Bochum, Germany, and the University of Michigan in the US — and entitled: (Un)informed Consent: Studying GDPR Consent Notices in the Field. The researchers ran a number of studies, gathering ~5,000 of cookie notices from screengrabs of leading websites to compile a snapshot (derived from a random sub-sample of 1,000) of the different cookie consent mechanisms in play in order to paint a picture of current implementations. They also worked with a German ecommerce website over a period of four months to study how more than 82,000 unique visitors to the site interacted with various cookie consent designs which the researchers’ tweaked in order to explore how different defaults and design choices affected individuals’ privacy choices. Their industry snapshot of cookie consent notices found that the majority are placed at the bottom of the screen (58%); not blocking the interaction with the website (93%); and offering no options other than a confirmation button that does not do anything (86%). So no choice at all then.
