Arguments against Observer-Expectancy
Honestly it is impossible to determine if the autism experiment is an example of observer-expectancy bias. But, I do have hope for all things so it is hope that will make me believe that what has happened to Lenny is NOT and example of observer-expectancy bias.
If it is helping the parents then what does it matter if the child is actually learning? Ö even though it may or may not work it still serves a positive purpose. You don't have to believe in miracles to appreciate the happiness they cause. Fraud or not it still helps people and should be allowed to continue.
