It doesn't say that they accounted for possible changes in item quality. Tide detergent claims that their new 80-oz bottle of laundry detergent can wash 64 loads just like the previous 100-oz bottle because it's more concentrated, and I suppose NPR (if they'd retained a sample of the previous product) could have brought that to a chemistry lab to test and verify that claim, but I have no idea how you'd objectively prove that an ounce of salsa had truly remained the same product.

Sure, but they are accounting for size shrinkage which the original poster was saying they didn't.

I don't really know how you can account for quality either. User surveys? Ingredient sourcing? But then again I think this kind of reporting is just a general barometer. Some other comments are pointing to data sources that might do more of this.

Laundry detergent is usually priced as cents per load by savvy shoppers. That would factor out smaller doses.

The amount of detergent per load is set by the manufacturer, who can injection mold that measuring cup in whatever size they want. FTA:

> The amount of liquid had shrunk to 92 ounces from 100 ounces before the pandemic, and the price had risen by a dollar. After that, the cost stayed the same, but the contents shrank to 84 ounces in 2024 and then to 80 ounces in December.

> The label continuously promised enough detergent for 64 loads of laundry.

> ...Tide specifically got the "most significant upgrade to its liquid formula in over 20 years," according to the company, with a "boosted" level of active cleaning ingredients and updated dosage instructions.

> "The result is superior cleaning performance in a smaller dose," a Procter & Gamble representative said.

Do you take them at their word for that? I'm specifically wondering whether the 84 ounce, 64-load bottle with a cap that measures out 1.3125 ounces per load contains the exact same liquid as the 80 ounce, 64-load bottle with a cap that measures out 1.25 ounces per load. I prefer powder detergent with a prewash dose, I know my clothes get clean, but I don't know that anyone outside a lab would be able to inspect clothes post-wash and notice the difference in cleanliness caused by the removal of 0.0625 ounces of detergent.

They have three ways to protect or boost profits: Raise prices, decrease quantities, or decrease quality. NPR and the

At some point it will be concentrated it'll be powder again ;-)
