What the study found
First and last stick best.
People who wrote down a list from memory recalled the first few and the last few items best: the serial position effect. Ours is a tap-to-recognise version, so your row may look different.
Bennet Murdock · Journal of Experimental Psychology, 1962
Why it matters
Memory keeps favourite bits and blurs the rest. That is why KOZMO asks how often specific things happen, not for a verdict on how things went.
It is for fun: the game does not measure you.
