Do you have a citation for what you’ve called the “recency bias”? I can’t seem to find a legit one outside of rags like “investopedia”.
There is the very well documented “recency effect”, which is a core part of Tversky and Kahneman’s Availability Heuristic (https://en.wikipedia.org/wiki/Availability_heuristic). This bias means that information that comes to mind easiest is more likely to be used for a decision, and as a result those items that are recent/fresh in your mind are most likely to inform a future decision or thought. That certainly is a bias that could be at play while programing, but it has nothing to do with “value”, but rather with “ease of access”.
