This phrase is a sophisticated way to start explaining why calculating statistical power after an experiment is finished is a bad idea. It's like telling a friend, 'Hey, checking the odds after the game is over is controversial because it doesn't actually tell you anything new.'

Venting to a fellow PhD student

Cultural Background
German universities emphasize 'Methodenkritik'. Students are expected to not just apply formulas, but to question their validity. Global movement, but very strong in Germany (e.g., Leibniz Institute). They advocate for pre-registration to avoid post-hoc fallacies. Swiss German academic writing is very similar to High German but may use slightly different punctuation rules in some contexts. Often uses even more formal titles and structures (e.g., 'Hochverehrter Herr Professor'), making this phrase a perfect fit.
Use 'da' for extra points
In academic writing, 'da' is preferred over 'weil' as it sounds more objective and established.
Verb Position
Always double-check that your verb is at the very end of the 'da'-clause. It's the #1 error for C1 learners.

What It Means
This phrase is the ultimate 'intellectual icebreaker' for researchers. It signals that you understand a deep flaw in statistical logic. When you say Post-hoc Poweranalysen sind umstritten, da sie, you are preparing to explain that these analyses are often redundant. They usually just reflect the p-value you already found. It’s a way of saying that looking backward to see if you had enough 'power' is logically circular. You're basically calling out a common mistake in scientific papers.
How To Use It
Think of this as a setup for a 'mic drop' moment in a seminar. Because it ends with da sie, you must follow up with a subordinate clause. This means your verb goes to the very end of the sentence. For example: ...da sie keine zusätzliche Information liefern. (because they provide no additional information). It sounds very polished and authoritative. You aren't just saying they are 'bad'; you are saying they are 'umstritten' (controversial), which is much more academic and polite.
When To Use It
You will mostly use this in university settings or professional research. It’s perfect for writing your Master’s thesis or during a PhD defense. If you are reviewing a colleague's paper and want to sound smart but fair, this is your go-to line. It also works well in a study group when you want to show off your methodological knowledge. It’s the linguistic equivalent of wearing a very nice blazer to a lecture.
When NOT To Use It
Do not use this at a bar, unless you are drinking with a group of very nerdy statisticians. If you tell a waiter that the menu is 'umstritten, da sie...', they will be very confused. Avoid it in casual texts to friends about weekend plans. It is far too heavy for daily life. Also, don't use it if you can't actually explain *why* they are controversial—you'll get caught in a logical trap!
Cultural Background
Germany has a massive culture of 'Wissenschaft' (science) and methodological rigor. German academics take their statistics very seriously. Being able to critique a method using precise language like umstritten is a sign of high education. There is a certain pride in being 'gründlich' (thorough), and pointing out logical fallacies in post-hoc power is a classic move in German academia to ensure the highest standards of truth.
Common Variations
You might hear Retrospektive Poweranalysen instead of Post-hoc. Or, someone might say ...werden kritisch gesehen (are seen critically) instead of sind umstritten. If someone is being more direct, they might say Post-hoc Poweranalysen sind irreführend (are misleading). But the umstritten version is the most common way to start a polite but firm academic disagreement.
Usage Notes
This is a strictly C1/C2 level academic expression. It requires perfect control over subordinate clause word order and is almost exclusively found in written scientific German or formal presentations.

In academic writing, 'da' is preferred over 'weil' as it sounds more objective and established.
