31、s to gather the range of observations that are necessary to speed up discoveries or to identify large-scale trends b the open-data shift poses a confusing problem for junior researchers,on the one hand,the drive to share is gathering official steam.since 2013,global scientific bodies have begun to t

32、hat support increased public access to research on the other hand,scientists disagree about how much and when they should share data,and they debate whether sharing it is more likely to accelerate science and make it more robust,or to introduce vulnerabilities and problems.as more joumals and funder

35、utation without the need for conventional metrics,such as publication in high-impact journals.D some fields have embraced open data more than others.researchers in psychology,a field rocked by findings of irreproducibility in the past few years,have been especially vocal supporters of the drive for

47、each for tthe data and software,in addition to the paper itself.and although some say that citations for software or data hace little currency in academia,they can have other benefits Mmany advocates think that transparent data procedures with a date and time stamp will protect ientists from being s

50、ce,partly because his fossilbased research depends on access to others data.he says that more openness in science could help to discourage what some perceive as a common practice of shutting out early-career scientists requests for data.Ocommunication also helps for those who worry about jeopardizin
