Q.Case Study (continued) — based on the Desmond Green interview transcript: what does the term 'political correctness' mean, and what is being referred to as political correctness in the interview?

Disability Definition — A First Look

Imagine you're trying to climb a staircase. For most people, that's a simple action. But if you're in a wheelchair, the staircase becomes a barrier — not because you can't move, but because the environment wasn't built with your situation in mind.

That's the core intuition behind disability: it's not just about a person's body or mind — it's about the gap between what a person can do and what the world expects them to do.

The Two Big Ideas

Historically, people thought of disability as a purely medical problem: "Your legs don't work, so you are disabled." That's called the medical model. It puts the entire problem inside the person.

But a deeper, more useful view is the social model. It says: a person may have an impairment (like blindness or paralysis), but they become disabled when society fails to accommodate them. A blind person isn't disabled when using a screen reader — they're disabled when a website has no text-to-speech option.

The Precise Definition

In most official contexts — including Indian law (the Rights of Persons with Disabilities Act, 2016) and the World Health Organization — disability is defined as:

Disability is an umbrella term for impairments, activity limitations, and participation restrictions. It refers to the negative aspects of the interaction between an individual (with a health condition) and that individual's contextual factors (environmental and personal).

Let's unpack that:

• Impairment — a problem in body function or structure (e.g., loss of a limb, low vision).
• Activity limitation — difficulty in executing a task (e.g., cannot walk, cannot read print).
• Participation restriction — difficulty in taking part in life situations (e.g., cannot attend school, cannot get a job).

The key phrase is interaction. Disability is not a fixed trait of the person — it emerges when a person with an impairment meets a barrier.

A Concrete Example

Take a student who uses a wheelchair.

• Impairment: Paralysis of legs.
• Activity limitation: Cannot climb stairs. …
