基于科学依据

You can use this phrase as a building block for your sentences. Usually, you’ll see it at the beginning to set the stage: 基于科学依据，我们建议... (Based on scientific evidence, we suggest...). Or, you can use it to describe something: 这个结论是基于科学依据的 (This conclusion is based on scientific evidence). It functions like an adjective or an adverbial phrase. It’s punchy, clear, and makes you sound like you’ve actually done your homework. Just remember to use the particle 的 if you are using it to describe a noun.

This is your go-to for professional settings. Use it in business meetings to justify a new strategy. Use it in school essays to support your thesis. It’s also great for those "serious" life talks. If you’re trying to convince your parents to try a new health supplement or explaining a skincare routine to a friend, this phrase adds instant authority. It signals that you value logic and truth. It’s the linguistic equivalent of showing your receipts.

Don't use this for matters of the heart or personal taste. Saying "My love for you is 基于科学依据" is a one-way ticket to a very awkward date. It’s too cold for romance. Also, avoid it in super casual, low-stakes situations. If someone asks why you like spicy food, saying it’s 基于科学依据 makes you sound like a robot. Keep it for when facts actually matter. Using it to decide which movie to watch is probably overkill, unless you're a real data nerd.

In modern China, there is a massive cultural emphasis on "Science" (科学). Since the "Science and Technology" push in the late 20th century, being "scientific" has become synonymous with being modern, advanced, and correct. You’ll see the word 科学 everywhere, from urban planning to parenting books. Using 基于科学依据 aligns you with these modern values of progress and rationality. It’s a high-status way to communicate because it moves away from old superstitions or unverified traditions.

You will frequently hear 有科学依据 (has a scientific basis), which is a bit more conversational. If you want to shut down a crazy rumor, you can say 缺乏科学依据 (lacks scientific basis). Another one is 根据科学研究 (according to scientific research), which is slightly more specific about where the info came from. All of these variations serve the same purpose: moving the conversation from "I think" to "We know."
