Ask Slashdot: Why Does Science Appear To Be Getting Things Increasingly Wrong?

azaris writes: Recent revelations of heavily policy-driven or even falsified science have raised concern in the general public, but especially in the scientific community itself. It's not purely a question of political or commercial interference either (as is often claimed when it comes to e.g. climate research) — scientists themselves are increasingly incentivized to game the system for improved career prospects, more funding, or simply because they perceive everyone else to do it, too. Even discounting outright fraud or manipulation of data, the widespread use of methodologies known to be invalid plagues many fields and is leading to an increasing inability to reproduce recent findings (the so-called crisis of reproducibility) that puts the very basis of our reliance on scientific research results at risk. Of course, one could claim that science is by nature self-correcting, but the problem appears to be getting worse before it gets better.

Is it time for more scientists to speak out openly about raising the level of transparency and honesty in their field?

    I think we are just beginning, more and more, to recognize the inherent limitations of terms like 'scientist'. Media outlets have to struggle to be the most clicked-on, first to break every story no matter how poorly researched or even conceived. The average citizen has access to resources that can verify the accuracy of almost anything. Unfortunately this tends to get lost among the increasingly noisy media. It also requires discipline, patience, and focus to actually apply such methods to anything. Most of the time we just take what we hear at face value - this has always been the way of things. Now, however, we feel somehow betrayed by our own conceptions when they turn out to be wrong.

    Also worth recognizing that science papers are not an attempt to define absolute truth, and people who use it as such (saying, "this paper says X, therefore X is true") are likely to be disappointed.

      I think there are two other related issues at play here:

      1. There has been a proliferation of relatively shoddy low-impact papers. Thanks to the Internet and the large scientific community, many of these are quickly flagged, but it's still a drag. Part of the reason for this is that the developed world (and more recently, aspiring nations) has been over-training scientists for a few decades, and a PhD is typically an essential requirement for most decent careers - which creates a big incentive to publish no matter how crappy the results.

      2. Because of our f***ed-up incentive system, there is an additional huge incentive to publish in ultra-selective high-profile journals, which means the result has to be sufficiently exciting (and "citation bait"). Naturally, this leads people to either cheat or (more often) be sloppy and careless. These failures attract the most attention for obvious reasons.

      Basically it's a natural side effect of the "democratization" of science. When basic research was just a gentleman's club centered at a relatively few elite institutions, there was much less incentive to game the system.

      If you're interested in reading papers outside of your area of expertise, this is what I'd recommend. Firstly, don't read the paper from front to back. Contemporary journal articles are way too dry for that and you likely don't care about all of the sections (eg, the experimental methods).

      Read the abstract to determine if you are actually interested in what the paper is going to discuss. The abstract will also give you a decent idea of who the writer considers to be their audience; if the abstract is completely and totally over your head, you're not likely to understand most of the paper.

      After that, you can skim the introduction to get a grasp of the context (and read any introductory subsections that you aren't familiar with or are fascinated by).

      In my field (and many/most others?), the story is generally told through figures of data and their captions. Generally, you can inspect the figures and captions and get a very good idea of what the paper is saying and what they're basing their conclusions on. You can jump to parts of the discussion section if you want more information than the captions are providing.

      The conclusions section ties it all together, but too often that section is just a wordier restatement of the abstract. The conclusions are also where you're most likely to find the speculative crap that excites journalists and potential sources of funding.

      If you're really into the topic, or it's in your field, you can dive in and read the sections that interest you, but a well crafted scientific paper should be able to tell the whole story through the figures and captions.
