Kultureller Hintergrund
This expression is a hallmark of Western academic and scientific discourse, which prioritizes 'impersonal' language to suggest objectivity. It became a standard fixture in research writing during the 20th century as the 'passive voice' became the preferred style for formal reports. It signals that the speaker is part of a professional or scholarly community.
The 'Passive' Power
Using 'It' as the subject makes you sound like an expert because it implies the facts are so strong they don't need a person to say them.
Don't Overuse It
If you start every sentence with this, your writing will feel heavy and boring. Mix it up with 'Research shows' or 'Data suggests'.

What It Means
Think of this phrase as the ultimate 'mic drop' for facts. It tells your reader that what you are saying isn't just a guess. It means that experts or scientists have already done the work. They have tested the idea and found it to be true. It’s like saying, 'Look, the evidence is right here.' It is very objective. It removes 'I' or 'you' from the sentence. This makes your statement feel like a universal truth rather than just a thought.
How To Use It
You usually put this phrase at the very beginning of a sentence. It acts as a powerful introduction. After the word that, you state the fact or the result of the research. For example, It has been demonstrated that sleep is good for memory. Notice how it sounds much more serious than saying 'I think sleep is good.' You are using the passive voice here. This is a classic move in English writing to sound more professional and unbiased. It’s perfect for when you want to sound like the smartest person in the room.
When To Use It
This is your go-to phrase for academic essays. Use it in university assignments or research papers. It is also great for formal business reports. If you are in a high-stakes meeting, use it to back up your strategy. It works well when you want to settle a debate with cold, hard facts. You might even use it in a serious email to a boss. It shows you have done your homework. It gives your words a lot of weight and authority.
When NOT To Use It
Please, do not use this at a casual Friday night party. If you say, It has been demonstrated that this pizza is delicious, your friends might think you’ve swallowed a textbook. It is way too stiff for dating or hanging out. Avoid it in casual texts unless you are being sarcastic. Also, don't use it if you don't actually have evidence. If you use it for a lie, you’ll sound like a very confident liar, which is worse! Keep it for the serious stuff.
Cultural Background
English academic culture values 'objectivity' above almost everything else. We like to pretend that facts exist independently of the people who found them. This phrase comes from the scientific method. It reflects a history of valuing empirical evidence over personal belief. In Western universities, using 'I' is often discouraged in formal papers. This phrase is the perfect tool to follow those rules. It makes the writer sound like a neutral observer of the truth.
Common Variations
You will often see similar phrases that do the same job. It has been shown that is slightly less formal but very common. Research indicates that is great for science contexts. Evidence suggests that is a bit softer if the proof isn't 100% certain. If you want to be even more intense, try It has been established that. All of these help you avoid saying 'I think' or 'In my opinion.'
