Ludwig's WRAP-UP
In summary, "It's improbable" is a robust and effective phrase for communicating low likelihood with a touch of sophistication. Analysis from Ludwig shows that it thrives in environments where evidence-based skepticism is required, such as in The New York Times or scientific reporting. While the contracted form is widely accepted in most professional writing, its uncontracted counterpart remains the gold standard for academic rigor. By using it correctly, writers can distinguish between what is merely unlikely and what is truly impossible, ensuring precise and credible communication.
