But what is the harm in excluding items from the learning process by burning them right away?
Wouldn’t that be an uncomplicated way to adjust the system?
You wouldn’t have to skip to a certain level just to be faced with another round of known and unknown items which poses the same problem once more.
Instead, you would get your lessons, go through the usual stages with all the new words but burn the basic ones right away. You’ll get way faster to those kanji and vocab that you actually have to learn and the system would stay intact (like, you could only level up with a certain percentage of items marked as guru+).
Also, if the system was adjustable to your own learning needs, people could finish all levels in a shorter time, which means less money spent. Even advanced learners would feel challenged by Wanikani right away, and everyone would be more motivated because their 500 reviews would not consist of 300 boring items, which makes it a chore more than a learning experience.
The only possible downside I see is that some learners would get lazy and burn items although they do not know them well enough but… there already are so many third party scripts that could be used to “cheat” the system and sabotage your learning process (like the Anki script, which doesn’t even require you to give any differentiated input). If you burn items you haven’t mastered yet, that’s your own fault then. Also, reviving is a thing.
All in all, an option to mark items as “known” would make learners progress faster, give them the items they actually need to advance, increase motivation and save them time and money.
Is there a reason not to add this option?
