Inspiration porn was coined by disabled comedian Maysoon Zayid and popularized by the disabled activist Stella Young in her Ted Talk. (I had initially thought it was coined by Stella Young, just due to the popularity of her Ted Talk, till I was corrected by disability activity Rebecca Cockley who knew both people)
Objectification, where the disabled are often seen as objects of pity, is also used as self-motivation by the non-disabled, who may view the contrast between their own lives and those of the disabled as a source of inspiration and motivation. This is very self-serving and primarily benefits the non-disabled. The object of pity (the disabled) is going to feel worse, while the 'pitier,' can walk away feeling inspired.
This requires acknowledging and addressing the systemic barriers and discrimination and on working towards real solutions, rather than relying on objectifying and dehumanizing portrayals of people with disabilities for motivation or inspiration.
