Seeing is No Longer Believing.
For decades, video and audio evidence were considered absolute proof. Today, Artificial Intelligence can map anyone's face onto any body and perfectly replicate their voice. When a politician's career can be destroyed by a fake video, or a war started by an AI-generated audio clip, how does society survive the death of objective truth? In this unit, we explore the vocabulary of digital deception.
- Deepfake (noun): A video of a person in which their face or body has been digitally altered so that they appear to be someone else, typically used maliciously or to spread false information.
- Disinformation (noun): False information which is intended to mislead, especially propaganda issued by a government organisation to a rival power or the media (unlike misinformation, which is an accidental mistake).
- Post-truth (adj): Relating to circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.
1. Raw Vocabulary: The Digital Illusion
Practice: drag a word, or select it and choose a gap.
1. The hackers used a AI programme to create a fake video of the president declaring war.
2. Before publishing the scandalous audio leak, journalists must completely its authenticity.
3. Because the footage was highly , millions of viewers believed the fake event actually happened.
4. Foreign intelligence agencies use deepfakes to intentionally the voters and cause chaos during an election.
5. If it becomes too easy to with video evidence, courts will no longer be able to trust security cameras.
6. Unfortunately, many users on social media are highly and will share a fake news article without reading it.
Choose a word, then choose a gap.
2. Idioms and Expressions
When discussing truth, deception, and the inability to trust what you see, native speakers use these idioms.
- "Seeing is believing." An old idiom meaning you need to see something with your own eyes to believe it's true (an idea deepfakes have destroyed).
- "To muddy the waters." To make an issue or situation more confusing and complicated, often intentionally to hide the truth.
- "To take something at face value." To accept something just as it appears to be, without questioning or investigating it further.
- "A smokescreen." Something designed to obscure, confuse, or mislead; a distraction from the real issue.
3. Reading: The Fake Election
Read about a highly dangerous hypothetical (or soon-to-be real) scenario.
Just days before the national election, a video went viral. It showed the leading candidate accepting a massive bribe from a foreign dictator. The video was a deepfake, but it looked flawless. Millions of gullible voters took it at face value.
Experts rushed to verify the footage, eventually proving it was a malicious fabrication designed to polarize the public. But the damage was done. The opposing party used the video as a smokescreen to attack the candidate's character. By the time the truth came out, the election was over.
This deceptive tactic proved that we have entered a post-truth era. If a rival nation were to release ten fake videos a day, it would completely muddy the waters. When criminals can seamlessly tamper with reality, the old saying that "seeing is believing" becomes our greatest weakness.
4. Grammar Focus: Conditionals for Unlikely Futures ('Were to')
When debating existential threats or drastic political policies, we often discuss scenarios that are highly unlikely or extreme (but still technically possible in the future). To sound formal and intellectual, we elevate the standard 2nd Conditional by using the "Were to" structure.
| Standard 2nd Conditional | Formal 'Were to' Conditional | Debate Example |
|---|---|---|
| If the government banned AI, the economy would collapse. | If the government were to ban AI, the economy would collapse. | Use this to emphasise that the condition is a theoretical or drastic action. |
| If a deepfake started a war, millions would die. | If a deepfake were to start a war, millions would die. | Note: We use "were" for EVERY subject (I, he, she, it, they). "If it were to happen..." |
Exercise A: Choose the Formal Conditional
1. If a malicious AI programme ____________ hack the voting machines, democracy would instantly collapse.
2. The public would lose all faith in the justice system if courts ____________ accept digital video as flawless proof.
Exercise B: Complete the Expressions
Type the missing words to complete these heavy idioms.
1. You can't just trust every video you see online; you should never take digital media at face .
2. The politicians released the fake audio clip specifically to confuse the voters and muddy the .
5. The Hot Seat: Debate Practice 🎙️

- How do we prevent a post-truth society when gullible people willingly share disinformation that aligns with their political beliefs?
- Use the 'Were to' Conditional: "If the government were to make all AI-generated media illegal, the tech companies would..." (Complete the sentence).
- When audio and video can be perfectly tampered with, how will police forces and courts ever verify evidence during a trial?
- Is it possible to completely eradicate disinformation without destroying free speech, or is chaos the permanent price of the internet?
