> They can’t do everything at once. Therefore, they cannot treat everything as equally important. We need to acknowledge that and draw from the experience of that process. Which (I will suggest) is also why traditionally issues related to "screen readers" are addressed before issues related to cognitive disorders. That too needs to be acknowledged and so far I have not read any proposal to address that imbalance. > It won’t be 100% accurate, but we can draw on experience, typical usage, and typical designs to inform a likely impact. This however is the concern raised by Gregg: "typical usage" - as for many disability needs, the user requirement is atypical for the individual user, as Gregg notes when he wrote "*Even a submit button may be incidental if the user cannot determine whether they should submit something or not*." > if you are on an shopping site the context is buying things Respectfully, that is a far too simplistic perspective. Many 'shopping sites' are more than just pure-play product listings and shopping cart functions. Often the site is a mix of marketing and sales: a makeup company will sell their makeup online for sure, but will likely also feature health and beauty "tips" via blog posts, social media activities and other forms of "sticky content" ( https://www.clinique.ca/wedding-prep-beauty-guide). While revenue generation may be the company's ultimate goal, the importance of the "sticky content" to draw in potential customers may be an equally or at times more important short-term business goal (i.e. if everyone sells the same widget at the same price, what are other ways of differentiating a site to give it a competitive advantage? Competition for "eyeballs" [sic] is the retail industry's #1 consideration... you have to get them in the "virtual door" before you can even contemplate making the sale.) As Gregg wrote earlier: "... *we always judge what is important by what is important/critical to us - or to our imaginations of what would be important/critical to others. And that has not worked out well in the past for all those that get left out.*..." I will suggest the reality is that *context is almost always personal*: each individual will have their own reasons for navigating to and 'consuming' the screen content. A significant majority *MAY* have the same or similar contextual reason (the 80/20 rule?), but as this thread touches upon, we need to also acknowledge and address the 20% (atypical) needs as well. So while context is indeed important, as an evaluation metric it is hardly (IMHO) dependable, due to the bias Gregg (and to a certain extent Shadi) previously noted.
