Research was conducted by collecting broad findings from data published in academic journals as well as from individual case studies specifically focusing on website design for individuals with IDDs. 

Research demonstrated that individuals with intellectual and developmental disabilities struggle with content that is cluttered and dense as well as with inconsistency, making it important to keep website elements minimal and organized while keeping page layouts predictable. 

Granting user control, providing system status messages, and including the most important information first reduces cognitive burden and alleviates confusion related to attempts to retrieve ambiguous site functions from memory.
