The problem is not accuracy -- the words from the problem phrases are never suggested either. Worse, on the three-word phrases, iOS goes back and changes earlier words to avoid completing the phrase, and removes the original from the suggestions.

I tried typing "propaganda" ten times with 100% accuracy. When it's preceded with "[left] wing", the accuracy drops to 0%.

It's still predictive. It's using the context of surrounding words, and guessing the whole phrase.

Try swiping "grocery lost" and it will predict "grocery list", even you swiped over "o" and not "i". "put", "pit" and "pot" are all exactly the same swipe, and it always has to guess which you want.

It really is always guessing, and never completely sure. Every good consumer predictive system has some guardrails. Not guessing "free tibet" for someone in China could keep them out of serious trouble.

Could then tune the confidence thresholds instead of block list? Probably. Are they censoring you? No, just tap the letters.

I swipe United, it gets it right the first time.

I swipe Ireland, it gets it right the first time.

I swipe “united ireland” a hundred times, it never work.

It’s not probability.

You swipe “grocery lost”, you get “grocery list”. It is probabilistic.

if you backspace and swipe again, you get "grocery lost". with "left wing propaganda" you can backspace and swipe 100 times, it never appears.

ask yourself, since you insist it's probabilistic: what is statistically more probable, "left wing propaganda" or "left wring propaganda"?

Tried this myself. Got 10/10 on propaganda, 0/10 on left wing propaganda, 10/10 on right wring propaganda.

I think that’s a bigger issue regardless of your political stance.
