Innovation, Peer Review, and Bees

This post was inspired by a couple of Twitter conversations by people I follow, as well as my own experience with peer-review and innovation. The first is from Hiroki Sayama, who is contemplating a range of peer review opinions on a submitted proposal.

I like the using the notion of entropy to describe a wide range of peer-review opinions based on the same piece of work. This reminds me of the "bifurcating opinion" phenomenon I sketched out a few years ago [1]. In that case, I conceptually demonstrated how a divergence of opinion can prevent consensus decision-making and lead to editorial deliberation. Whether this leads to subjective intervention by the editor is unclear and could be addressed with data.

Hiroki points out that "high-entropy" reviews (wider range of opinions) represent a high degree of innovation. This is an interesting interpretation, one which leads to another Twitter conversation-turned complementary blog posts from Michael Neilsen [2] and Julia Galef [3] on the relationship between creativity and innovation.

In my interpretation of the conversation, Michael point out that there is a tension between creativity and rational thinking. On one side (creativity) we have seemingly crazy and irrational ideas, while on the other side we have optimal ideas given the current body of knowledge. In particular, Michael argues that the practice of "fooling oneself" (or being overly confident of the novel interpretation) is critical for nurturing innovative ideas. An overconfidence in conventional knowledge and typical approaches both work to stifle innovation, even in cases where the innovation is clearly superior.

Feynman though that "fooling oneself" was generally to be avoided, but also serves as a hallmark of scientific rationality. However, the very act of thinking (cognitive processes such as focusing attention) might be based on fooling ourselves [4], and thus might define any well-argued position. 

Julia disagrees with this premise, and thinks there is no tension between rationality and innovative ideas. Rather, there is a difference between confidence that an idea can be turned into an artifact and confidence that it will be practical. Innovation is stifled by a combination of overconfidence in practical failure combined with a lack of thinking in terms of expected value. I take this to be similar to normative risk-aversion by the wider community. If individual innovators are confident in their own ideas, despite the sanctions imposed by negative social feedback, they are more likely to pursue them.

Nikola Tesla's approach was "irrational", it was also a sign of his purposeful self-delusion and perhaps even his social isolation from the scientific community [5]. Remember, in the context of this blogpost, these are all good things.

Putting this in the context of peer review, it could be said that confidence or overconfidence is related to the existence and temporary suspension of sociocultural mores in a given intellectual community. A standard definition of social mores are customs and practices enforced through social pressure. In the example given by Michael Neilsen, fooling oneself in order to advance a controversial position requires an individual to temporarily suspend social mores held by members of a specific intellectual community. In this case, mores are defined as commonly-held knowledge and expected outcomes, but can also include idiosyncratic practices and intuitions [6]. From a cognitive standpoint, this may be similar to the requisite temporary suspension of disbelief during enjoyable experiences.

While this suspension allows for innovation, violations of social mores can also lead to a generally negative response, including moral panics and the occasional face full of bees [7]. Therefore, I would amend Hiroki's observation by saying that innovation is marked not only by a wide range of peer-review opinion, but also by universal rejection. Separating the wheat from the chaff amongst the universally rejected works is work for another time.

The price of innovation equals a swarm of angry bees!

Embryology Special Issue

Me and my colleagues are pleased to announce an upcoming special issue of the journal Biology (Basel). The topic is "Computational, Theoretical, and Experimental Approaches to Embryogenesis" (see announcement). Our view of what constitutes embryogenesis research is rather broad, spanning experimental studies, cellular reprogramming, bioinformatics, and artficial life. Therefore, we seek submissions from a wide variety of researchers and article types.

As the lead editor, I will take any questions you might have about interesting ideas, types of articles, or if you are interested in peer-review. As noted on the poster, the deadline for submissions is August 31, 2017. Looking forward to an excellent issue.

UPDATED (5/17):
With the initial dealine fast approaching, we have decided to extend the submission deadline to December 31.

Announcing our Google Summer of Code 2017 Students

As mentioned in a previous post, the OpenWorm Foundation (and DevoWorm group) has been receiving application for this year's Google Summer of Code. We have now selected our student applicants and projects to be awarded the internship. We had a very good group of applicants this year, so congratulations go out to everyone who applied!

Shubham Singh will be working on the model completion dashboard project, which is a general tool for the OpenWorm community. Siddharth Yadav will be working with me and the rest of the DevoWorm group to quantify and analyze secondary microscopy data that capture the process of embryogenesis for C. elegans and other organisms [1]. Good luck!

Thanks to the INCF for coordinating the selection process!
