The clear failure here is that research is at its best when it is fresh and relevant. User research is only beneficial if it leads to great product experiences for users. The further research insights are from their practical use, the less impact they are going to have.
Lastly, this doesn’t work because good research takes time. You need time to get out into the field; you need time to understand users; and you need time to follow as many insights to dead ends as it takes, before you find that one core insight that unlocks product genius.
