Ya'll should pardon me as i'm also about to
As much as this is true to an extent, we're however mostly responsible for the dumb words recommended by either our default or custom mobile keyboards.
Yes! Almost all of us have a predictive keyboard on our smartphone, which suggests upcoming words for super-fast typing. Even so, they're not perfect, and sometimes turn up hilarious results. Luckily, it's not hard to train our keyboard to understand you, once you know how it works.
In a basic form, keyboard prediction uses text that we enter over time to build a custom, local "dictionary" of words and phrases that we've typed repeatedly. It then "scores" those words by the probability we'll use it again.
For example, if we type in "lifehacker" and our keyboard has never seen us use it before, it'll offer to correct it to another phrase that it thinks is more likely (no, I don’t mean “lifejacket”). We have three options: We can accept one of the corrections, we can ignore the word and leave it as is, or we can add it to our personal dictionary so it won't bother us when next we type it again.
If we accept a correction, obviously the keyboard will continue to assume the word is wrong, and offer corrections in the future. If we add it to our dictionary, the keyboard "learns" the word immediately, and will offer it up the next time we enter a spelling pattern that's close to those keys, or use similar words before and after the phrase but misspell "lifehacker."
Things get interesting if we ignore the word—good predictive keyboards even use our lack of action to learn from our typing habits. The first or second time we ignore the word, it'll assume it's not a misspelling, but not a word we use often enough to be presented with in similar usage patterns. If we ignore it a third or fourth time (how many times depends on the specific keyboard), our keyboard will mark it as a future probable choice, and start presenting us with it when we type similar words or sentences.
I hope this further assist us train our keyboards so we can henceforth conveniently;
