Since accommodating multiple methods increases the complexity of the system, the number of methods for any given task should be limited to two—one for beginners, and one for experts.
It was found, that irrespective of gender, people rate individuals in high face-ism images as being more intelligent, dominant, and ambitious than individuals in low face-ism images.
If the costs associated with interacting with a design outweigh the benefits, the design is poor. If the benefits outweigh the costs, the design is good.
For example: How long is too long for a person to wait for a web-page to load? The answer to this question is that it depends on the benefit of the interaction.
It was found that images of men in magazines, movies, and other media have significantly higher face-ism ratios than images of women.
This appears true across most cultures, and is thought to reflect gender-stereotypical beliefs regarding the characteristics of men and women.
As the level of exposure to the novel art increases with time, familiarity with these unconventional objects of art also increases and results in greater acceptance and popularity.

Constrains, as methods of limiting the actions that can be performed on a system, simplify usability and minimize errors. For example, dimming or hiding options that are not available at a particular time effectively constrains the options that can be selected.
Proper application of constraints in this fashion makes designs easier to use and dramatically reduces the probability of error during interaction. Simply put; constrains simplify usability and minimize errors!
