文化的背景
In American business culture, this phrase is used to project confidence and 'data-driven' leadership. It is often followed by a 'call to action.' British academic writing heavily favors this phrase for its 'understated authority.' It sounds more modest than 'I have proven' but is equally definitive. While Germans value directness, when writing in English, they often use this phrase to match the 'international' academic standard of objectivity. Japanese professionals using English will use this phrase to avoid the first person 'I,' which aligns with their cultural preference for group harmony and humility.
The 'That' Rule
Always follow this phrase with 'that' to introduce your finding. It keeps your sentence structure clean and professional.
Don't Overuse
If you use this phrase more than twice in a single report, it starts to sound repetitive. Mix it up with 'The data suggests' or 'The findings indicate.'

What It Means
Think of this phrase as your 'I told you so' button in a suit. It is a way to say your study proved something important. You are not just guessing; you have the hard facts. It sounds very official and very serious to the reader. It tells them that the evidence is now clear.
How To Use It
You usually put this at the end of a paragraph or section. First, you show your data or facts to the reader. Then, you use this phrase to sum everything up. It acts like a bridge to your final conclusion. Always follow it with the word that and a clear statement.
When To Use It
Use it in university essays or professional business reports. It is great when you want to look like an expert. Use it during a big presentation to impress your boss. It works best when you have actual numbers to back it up. It gives your argument a sense of finality and strength.
When NOT To Use It
Do not use this at a casual party with friends. If you say 'This analysis has demonstrated you are late,' you sound robotic. Avoid it in casual texts or quick emails. It is way too heavy for a quick chat about lunch. Save it for when you are wearing your 'smart' hat.
Cultural Background
This phrase comes from the world of science and formal logic. In English-speaking academia, we value objective language very highly. We like to pretend the data is speaking for itself. It removes the 'I' to make the argument feel more powerful. It suggests that anyone looking at the facts would agree.
Common Variations
You might see The study indicates or The results show. If you want to be less certain, try The data suggests. For a stronger punch, use The evidence proves. Each variation changes the 'strength' of your claim slightly. Demonstrated is right in the middle—strong but professional.
使い方のコツ
This is a high-formality expression. It is almost exclusively used in written reports, academic papers, and formal presentations. Avoid using it in spoken conversation unless you are being intentionally ironic or humorous.
The 'That' Rule
Always follow this phrase with 'that' to introduce your finding. It keeps your sentence structure clean and professional.
Don't Overuse
If you use this phrase more than twice in a single report, it starts to sound repetitive. Mix it up with 'The data suggests' or 'The findings indicate.'
Objectivity is Key
Remember that the goal of this phrase is to sound objective. Avoid adding emotional words like 'This analysis has demonstrated the *terrible* truth...'

よくある質問
10 問Yes, but it changes the meaning slightly. 'Demonstrated' (past tense) implies the analysis is old. 'Has demonstrated' (present perfect) implies the results are relevant right now.
In formal writing, yes. 'Demonstrated' sounds more rigorous and scientific. 'Shown' is perfectly fine for neutral or slightly informal contexts.
Only if you are being sarcastic or funny. It is far too formal for casual texting.
An 'analysis' is the process of looking at data. A 'study' is the whole project. You can use either: 'This study has demonstrated' or 'This analysis has demonstrated.'
In modern academic writing, 'I have demonstrated' is becoming more acceptable, but 'This analysis has demonstrated' is still the safer, more traditional choice for high formality.
Absolutely. Whether you are analyzing numbers or interviews, the phrase works to introduce your conclusions.
You can use the passive voice: 'It has been demonstrated by this analysis that...'
Then do not use 'demonstrated.' Use 'This analysis suggests' or 'The results are inconclusive.'
No, it is a 'strong' verb because it implies proof. 'Suggests' is a 'weak' or 'hedging' verb.
Yes, in a formal speech like a keynote address or a presentation to a board of directors.
