Here is some examples to consider.

Differences live with is not the same
A major problem when understanding a person's difficulties is that can they can be generalised with assuming that their difficulties and limitation of abilities are the same for all people. This leads to negative misinterpretations when a person with hidden differences when they are easily disbelieved. In reality the kind of difficulties a person lives with varies from person to person, even within the same condition.

An assumption that any difficulties can disappear through employment and fitness
One of the most common misinterpretations assumes that if a person with differences participates in physical activity and access employment assumes that their difficulties would automatically disappear. This information is false.

Obsessions of curing
There are some false assumptions related to cures related to the difficulty a person lives with. All hidden differences are not curable. This is despite some people with ADHD accessing certain medications to manage the effects on their difficulties.


Lifestyle
There is no generalisation on the lifestyle of hidden differences in their tastes, interests or passions. Some have attempted to make generalise stereotypes and make certain association with a specific lifestyles. This kind of generalisation causes harmful stigma and divide hidden differences from the rest of society.

Persistent intolerance
Some people have unrealistic expectations who thinks that person with hidden differences should face tough discipline and an excess amount of intolerance which assumes their differences would less prevalent. This approach is an extremely dangerous and maxises the amount of harm to their circumstances. Also, it can cause damaging side effects, leading to an high amount of stress, anxiety, mental health and can lead to mental instability. This can even can escalate towards depression and even worse.

Healthcare & support presumptions
Many people with differences are not taken into consideration in their experiences or circumstances. This means if a person with differences is addressing serious issues which affect their lives, such as prejudice, discrimination can be taken less seriously as a citizen and only seen as healthcare or a support matter. This can damage a person with hidden differences place in society.
