In all of the workplaces that I've been to so far, there is a strong conviction that estimating the work in the story points leads to the more accurate estimations than using old-school work-hours. This belief seems to be also wide-spread in the various online resources (websites) related to the topics of planning the work.
Many of my supervisors as well as my current colleagues hold this opinion too. However when approached about this point they fail to point me to any source nor evidence that would support this view.
Is there any evidence that estimating the work in story points leads to more accurate estimations than estimating the work in hours?
