I became a guerrilla UX fighter back in 1995.

Me in my guerrila days

I've been underground for many years, but recently decided to ditch the Kalashnikov, get out the trenches, and take a more formal approach to the topic.

Currently taking an MSc in Human-centred Interaction Design at City University, London.

I specialise in complex system, cognition and aesthetics; my current role is a UX/Product designer.

@Angelo.Hannes Could you propose a better design in the SO question you have referenced? I argue there isn't a better design, and really hope I'm wrong!

@Angelo.Hannes Sorry to say - but the recommendation is idiotic. There are gazillions of examples where the user must make an exclusive choice, but you don't want to provide a default. Perhaps a prime example is likert scales - any default will prime the users. That's exactly why no browser implements the standard.

comment Adding a “none of the above” option to a list of checkboxes
But we shall also account for the fact people are intelligent and given the context, the option "none of the above" implies that choosing it will disable all other choices. But is this the optimal design? I'd argue it isn't. You should also consider errors and recoverability - invisible logic makes the whole story far more complex.

comment Adding a “none of the above” option to a list of checkboxes
I disagree with this view. You should consider mental models and visibility. Checkboxes, by convention are boolean controls and can be composed into a multi-selection group. That's what users expect. Any 'behind the scenes' logic is invisible to users. That is, if you put a user in front of a wireframe and ask them how this would behave (their expectations - which we all build while interpreting an interface) they could easily be confused. The controls imply one thing, the labels - another.

@AdamStone You can always provide a 'Mark all as No' button.

I'm pretty sure the client requires explicit action for the 'No'. That's why I though more 'No's would mean for the client less 'I didn't pay notice'. It's an example where business goals win over usability.

comment Accessibility (color contrast) of report inappropriate function
Could you please clarify the following: 1) What's the relationship between the (tags?) images and the question. 2) How do you know that fail the AA compliance? 3) What do you mean by 'acceptable'?
