In the year 1610, Galileo observed a ring-like shape around a distant planet (Saturn). After realising the significance of his discovery, Galileo wanted to record it to be able to claim it as his own contribution once it was announced. To do that, he wrote a letter to a colleague stating the following: “smaismrmilmepoetaleumibunenugttauiras. That meaningless text was Galileo’s encoding of what he really wanted to say: “Altissimum planetam tergeminum observavi”, which translates to: “I have observed the most distant planet to have a triple form”. At the time, encoding was the only way scientists could guarantee no one stole their findings.

Luckily, these days, scientists have many venues where they can claim ownership and declare victory on solved problems. Publication in journals, conference proceedings, surveys, studies, reports, white papers, books, and other forms of documentation are official outlets for scientific discoveries. Such publications constitute the body of knowledge of a certain scientific domain; contributing to this ‘body’ is not arbitrary, it is a rather well-defined process. Peer-reviewing for example is one method of evaluating research submissions before they are accepted (for a journal publication or a presentation at a conference).

The importance of the mentioned publications stems from the notion that they form the basis of reference for many aspects of our lives. Most of the time, we tend to point to studies and use them as part of a professional or friendly discussion, in policy making, on TV, radio, media debates, and in decision-making. An experiment is usually required for the publication to be adopted and/or deemed scientific. The results of an experiment indicate a success or a failure of a certain proposed hypothesis.

It is common to see published studies presented in other “cooler” forms (such as in websites, magazines, or newspapers). We often see titles such as: “a glass of red wine equals one hour at the gym”, ”artichokes reduce the risk of cancer”, or the famous (but inaccurate) “green jelly beans cause acne”; among many other surprising correlations that we sometimes accept, share, and even use for life-changing choices.

The sad reality is that some inaccurate studies are cherry-picked by profit-driven media organisations, and sometimes find their way into conventional wisdom and become, for many, facts. A recent poll showed that 65 per cent of experimental results in journal articles cannot be reproduced if executed again. Furthermore, 75 per cent of medical studies suffered from a false-positive outcome, but what does that mean? If someone runs enough tests, a false-positive will almost certainly emerge. For example, assume that you flipped a coin six times in January and got four heads and two tails; and then flipped the coin again in February, and got four tails and two heads; can you then make the following claim: “In January, heads have double the chance of emerging when flipping a coin”? The answer is no; because if you flip the coin one million times every month, all months will get almost 50 per cent heads and 50 per cent tails. The point here however is that flipping a coin one million times every month is very expensive! And so is running most scientific experiments.

Moreover, and in many cases, outcomes are only accurate when measured with a set of pre-existing conditions or biases (such as a recency bias or an anchoring effect). Other experiments might have data biases – such as: data sampling methods, model overfitting, or using a subset of a dataset that yields to the desired outcome of an experiment.

Some mathematical principles however, such as statistical confidence, significance, p-value, and correlations are used to evaluate experimental results. Those principles can help evaluate the correctness of research. The main problem is that there are many other institutional reasons why most reported scientific experiments tend to be inaccurate:

  • The main career currency for academics is publishing: Academics are encouraged to publish as many papers as possible (i.e. publish or perish!). Hence, in some cases, more papers with less impact are better than fewer papers with noticeable impacts. The impact factor is one way of measuring the importance of a publication, but that is ignored most of the time.
  • There is little to no value in reproducing or verifying published research. Although duplicating an experiment would greatly benefit a scientific field, replicating studies is not rewarded in the scientific community.
  • Scientists don’t get paid for peer-reviewing submitted works: There is no unified standard for reviews. Reviews, in many cases are not extensive, and can be limited to one or two superficial sentences (something most scientists have witnessed at some point of their careers).
  • Science and technology policies: we take Open Internet (freedom to browse the web without explicit consequences) for granted. Net-Neutrality has protected us from the domination of internet providers, and any potential control of our seamless pursuit of everything that is online! The biggest and most recent danger to our liberties and freedoms would be taking that right away – this is a heavily debated topic these days.

  • Most importantly, Open Science: There is a serious lack in sharing material/resources that are used to creating the building-blocks of a research experiment. These blocks include: 1. the raw data used in and experiment, 2. the pre-conditions of an experiment, 3. the code, 4. software used, 5. experimental setup, and 6. environmental information.

Therefore, for science to be open (Open Science), those six pillars (and potentially others) need to be available (open). That is essential in addressing the increasing demand in re-evaluating the current scientific process. In the early 2000s, the internet’s own boy, Aaron Swartz (please see the author’s note in the comment section), took a stab at creating a repository of scientific papers for free and public access; and established the Open Access Manifesto – however, Aaron’s story didn’t have a fruitful or happy ending. He was prosecuted with two counts of fraud, before committing suicide in 2013.

There are some silver linings in the story of Open Science. Most journals now present a form of free-to-the-public publishing through what is known as Open Access. Open Access is usually expensive for the authors (it could cost a couple of thousand dollars to publish a paper), albeit free to the public. Another ‘open’ initiative is the Open Data Initiative. Open Data demands federal agencies to share their public data in machine-readable formats with the public. Many journal publications have recently been asking the submitters to send their data sets along with the paper. As for code and software, initiatives such as Open Source, Open AI, GitHub, and Google Open Source have been advocating, publishing and hosting software code with the public (for free).

If you believe that access to science is a human right (as I do!), Open Science is the direction that we all need to adopt. All scientists, researchers, and publishers need to participate in the process of ‘opening’ the sciences to the masses. The mentioned pillars (Open Data, Open Source, Open Access, and Open AI) are possible to accomplish, but the most difficult goal will be the seventh pillar: an Open Mind on Open Science by all parties involved.
