Research has shown that

You’ll almost always find this phrase at the very beginning of a sentence. It sets the stage for the 'punchline' or the core fact you want to deliver. For example, if you're trying to convince your friend to stop scrolling TikTok at 2 AM, you might say, Research has shown that blue light ruins your sleep. Notice how the word that acts as a glue, connecting the authority of 'research' to your specific claim. You can also use it in the middle of a sentence to justify a point you’ve just made. For instance: 'I always take a nap after lunch because research has shown that a twenty-minute rest boosts productivity.' It’s versatile, but it requires a full clause to follow it. It’s like a setup in a comedy routine, but instead of a joke, you’re delivering a dose of reality. Just remember: research is an uncountable noun in English. Never say 'researches.' It makes you sound like a robot that needs a software update.

This phrase lives in the 'Formal' to 'Neutral' neighborhood. You’ll see it all over academic papers, news reports, and professional presentations. It’s the bread and butter of journalists and professors. However, it’s also perfectly at home in a serious conversation with friends or a persuasive Instagram caption. If you’re writing a LinkedIn post about 'mindset,' this phrase is basically mandatory. On the other hand, it might feel a bit too stiff for a casual text about what pizza to order. You wouldn't say, Research has shown that pepperoni is the superior topping. That’s just being dramatic. Unless, of course, you actually have a pepperoni study, in which case, please share the link. In professional emails, it’s a great way to push back on a bad idea without making it personal. Instead of saying 'I think your plan is bad,' try 'Research has shown that this approach often leads to higher costs.' It’s the polite way to drop a truth bomb.

You’ll hear this phrase everywhere from Netflix documentaries to your local gym. A personal trainer might tell you, Research has shown that lifting weights is better for longevity than just doing cardio. Or, while watching a health vlog on YouTube, the creator might start a segment with, Research has shown that drinking green tea can improve focus. In the world of social media, it’s often used to debunk myths. A TikToker might post a video saying, Research has shown that you don't actually need 10,000 steps a day to stay healthy. It’s even in the world of dating apps. Some 'relationship experts' on Instagram love to start their captions with, Research has shown that the first three months of a relationship are the most critical. It’s everywhere because everyone wants to be right, and nothing says 'I'm right' like the word research.

Use this when you want to persuade someone or provide context for a decision. It’s perfect for job interviews when you need to explain why your methods work. For example, 'I prioritize team building because research has shown that happy employees are 20% more productive.' It’s also great for educational content. If you’re a tutor or a content creator, it builds trust with your audience. Use it when you’re citing a specific study or a general consensus in a field like psychology, medicine, or economics. It’s also a useful tool for self-improvement. Reminding yourself that research has shown that meditation reduces stress can help you stick to your routine. Basically, use it whenever you want to move from 'I feel' to 'we know.' It’s the ultimate confidence booster for your sentences.

Don't use this for personal preferences or subjective feelings. If you say, Research has shown that my mom makes the best lasagna, people are going to ask for the data set. Unless you’ve surveyed 500 people and run a double-blind taste test, just say 'I love my mom's lasagna.' Also, avoid it when you're being vague or lazy. If you say it just to sound smart but don't actually know what research you're talking about, a savvy listener might ask, 'Which study?' and then things get awkward fast. It’s also a bit much for very casual settings. If you’re at a bar with friends, constantly citing 'research' can make you seem a bit condescending. Nobody likes the 'well, actually' guy. Use it sparingly, like a strong spice. Too much of it, and you’ll ruin the flavor of the conversation.

One of the biggest pitfalls is treating research like a countable noun.

• ✗ Researches have shown that...
• ✓ Research has shown that...

English speakers treat research as a single, collective concept. Another mistake is forgetting the word that.

• ✗ Research has shown people need sleep.
• ✓ Research has shown that people need sleep.

While you can sometimes drop that in casual English, keeping it makes you sound more professional and clear. Also, watch out for the 'empty' use.

• ✗ Based on the research, it has shown that...
• ✓ Research has shown that...

The first one is redundant and clunky. It’s like wearing two hats at once. Finally, don't use it to present something that is actually just common sense. 'Research has shown that if you don't eat, you get hungry' is a waste of a perfectly good phrase. We know, Dave. We know.

If you find yourself saying research has shown that too many times in one paragraph, you might want to switch it up. You can use Studies suggest that for a slightly softer tone. It implies that while the data points one way, it’s not necessarily a closed case. Evidence indicates that is another strong choice, often used in legal or very technical contexts. For something more modern and punchy, try Data shows that. This is very popular in tech and business circles. If you want to be more specific, you can say Clinical trials have proven that or Psychological studies reveal that. In casual conversation, you might just say They say that... or I read somewhere that..., but those lack the punch of the original. Use the variations to keep your writing fresh, but keep the core meaning the same.

Is research always singular? Yes, in English, research is an uncountable noun, so you should always use has instead of have. Can I use it for my own small survey? Technically, yes, but it’s better to say 'My survey found that' to be more honest about the scale. What if the research is old? You might want to say 'Previous research showed that' or 'Early studies indicated that' to show you're aware of the timeline. Is it too formal for a text? It can be, so maybe save it for when you're actually debating a topic or sharing a cool fact you learned. Why do people use it so much? Because it’s a shorthand for 'trust me, I’m not just guessing,' which is very powerful in any language.
