Let’s dive in.
What is Explainability?
In simple terms, explainability refers to the ability of an AI system to provide evidence, reasoning, or support for its decisions and processes. The principle of explainability states that for a system to be truly explainable, it must supply evidence or reasoning for its actions.
Essentially, when AI systems can clarify how and why they arrived at an outcome, users feel confident in their reliability.
Think of it like asking a friend why they made a specific choice. If they can explain their reasoning clearly, you’re more likely to trust them. This is the reason for explainability in trustworthy AI.
At its core, it’s about offering a window into the machine’s thought process.
However, this principle is independent of whether the explanation is entirely accurate or perfectly clear.
Why is Explainability Important?
1. Trustworthiness of AI

Would you trust it with your health?
Explainability, in trustworthy AI, helps bridge the gap between complex algorithms and human understanding, making users more comfortable relying on AI.
2. Accountability
Accountability ensures responsibility. It implies that AI systems can be held responsible for their decisions.
Without explainability for trustworthy AI, accountability becomes impossible.
How can we question an AI’s judgment if we don’t understand its logic?
By making processes transparent, explainability in trustworthy AI ensures that systems operate ethically and responsibly.
3. Compliance
Legal frameworks like the General Data Protection Regulation (GDPR) mandate transparency in AI systems.
Explainability plays a pivotal role in ensuring compliance by providing insights into how decisions are made.
This is especially critical in sensitive fields like finance, healthcare, and law enforcement.
