YouTube watch history makes it easy to find videos you recently watched, and, when it’s turned on, allows us to give relevant video recommendations. You can control your watch history by deleting or turning off your history. If you delete some or all of your watch history, YouTube won’t base future video recommendations on that content. Any videos that you watch while history is turned off won’t show up in your history.
For “recommendations” read algorithms.
Might I suggest turning off watch history in YouTube before it leads us up the garden path.
If we look up something on YouTube the algorithm will dump lots of the same on your YouTube account.
