Principles Not Included in Design Journal #1

Accessibility:
Remember the Milk has been designed for above average web usesr; tech-savy individuals who are comfortable with a range of cutting edge products. Thus, I would argue that RTM was not designed with accessibility in mind. It was designed to meet needs of a niche market, not “to be usable, without modification, by as many people as possible”.

Advance Organizer:
In the RTM application, all of the information it displays has been provided by the user. There is no new information for the users to learn and as such, the advance organizer principle does not apply.

Attractiveness Bias:
There are no people (just a cow) anywhere in the Remember the Milk application. As such the attractiveness bias principle does not apply.

Closure:
I could not find an obvious example of closure anywhere in the Remember the Milk application. It seems that the RTM designers were explicit in ensuring that the tool's features could easily be perceived as "multiple, individual elements".

Cognitive Dissonance:
RTM is, essentially, the digital equivalent of a pen and paper to do list. For this reason, there is limited need for users to "seek consistency among [their] attitudes, thoughts and beliefs" about their "to dos" - they just write them down and cross them off as they are completed. Thus, the principle of "cognitive dissonance" does not apply.

Common Fate:
Generally speaking, there is very limited "motion" in the Remember the Milk tool. Users can "move" tasks in the sense that they can individually move them up and down by changing their priority. but this provides limited, if any, for grouping by common fate. Thus, the principle would not apply.
