Economics Is Not Rocket Science – It’s Even More Complicated || #MarketingThema

par marketingthema

Authored by Gary Galles via The Mises Institute,

Over the years, I have heard multiple different things described as “not rocket science.” The implication was always that rocket science was just about the hardest thing to do, making virtually everything else easy by comparison. As an economics professor over many of those years, I have increasingly come to object to that characterization. I think the questions of social coordination that economics addresses may not require “rocket science,” but are in many ways much more complex and difficult, especially when it comes to imposing control.

After all, we have successfully sent rockets to many places in our planetary neighborhood, demonstrating a tolerable ability to solve enough of the relevant problems, yet economic policies remain known for causing more harm than help.

As Peter Boettke once led off a post, “Political economy ain’t rocket science. But it is a discipline that forces one to focus on ideas and the implementation of ideas in public policies.” And the more one tries to control, the more those ideas and implementation issues stack up against the possibility, much less the probability, of effectiveness.

In one important sense, rocket science is simply vector addition of the relevant forces. And the relevant relationships for generating rockets’ thrust are governed by physical laws and relationships that are stable and mathematically expressible. That is why one website deviated from rocket science orthodoxy, under the title “Rocket science is easy; rocket engineering is hard.” The problem is one of accurately measuring the needed information and controlling the relevant forces—that is, engineering things (often with millions of parts) so that they work as intended.

A great new ressource for those using R ! An extension of the `ggplot2` package for creating graphics with details from statistical tests included

par marketingthema

ggstatsplot` is an extension of the `ggplot2` package for creating graphics with details from statistical tests included in the plots themselves and targeted primarily at behavioral sciences community to provide a one-line code to produce information-rich plots, which can either be used for quick data exploration or for publications/reports/notebooks/etc:
https://cran.r-project.org/…/packages/ggstatsplot/index.html

Currently, it supports only the most common types of statistical tests (parametric, nonparametric, and robust versions of t-tets/ANOVA, correlation, and contingency tables analyses):

– violin plots (for comparisons *between* groups or conditions),
– pie charts (for categorical data),

On y parle du travail, des villes, du stop, du covoit, de la vie en fourgon, du voyage à pied, du temps et de la liberté. Un film auto(mobile)-produit sans argent mais avec la conviction qu’il est nécessaire de remettre en cause notre dépendance à la bagnole.

What is an epistemicide? Decolonization of knowledge

par marketingthema

A simple example, to start with! Each time when in your bibliography or scientific work you cite 90% of the time authors from the north despite the fact that similar works are conducted in the south, you are committing an epistemicid! You are making other productions invisible and marginal by giving an exclusive legitimacy to only some circles of knowledge production.

Another example, is the Islamic tradition of the « halaqa » in producing knowledge and as a research and academic methodology. A form or method that existed in the Islamic Spanish era, and that no longer exists today in the academic world.

A definition according to Quora: « Its a systematic destruction of any indigenous knowledge base. Any knowledge which doesn’t converge with the perpetrator’s knowledge system. It doesn’t believe in fusion or exchange of knowledge but complete disregard of the other’s knowledge. »

Tackling the MSI Research Priorities: Which Methods to Use? #MSI #2018

Marketing science has developed a large array of research methods to tackle important questions for marketing management. These were recently summarized and illustrated in the Handbook of Marketing Analytics. But which method should be used for which question? Natalie Mizik and Dominique Hanssens will select three of the 2018-2020 MSI Research Priorities—to be announced at the Spring 2018 Board of Trustees Meeting—and review successful applications of various research methods to address these questions and invite audience comments.

Science is in a reproducibility crisis – how do we resolve it?

par marketingthema

Publish or perish: Scientists are not given incentives to replicate others’ results, and even when they do so on their own steam, negative findings often go unpublished… this is not science nor research! this is a spectacle! Pusblish or perish culture generates PUBLISH AND PERISH results

Over the past few years, there has been a growing awareness that many experimentally established “facts” don’t seem to hold up to repeated investigation.

This was highlighted in a 2010 article in the New Yorker entitled The Truth Wears Off and since then, there have been many popular press accounts of different aspects of science’s current reproducibility crisis.

These include an exposé of the increasing number of retractions by scientific journals and damning demonstrations of failures to replicate high profile studies.

Articles in recent days have discussed how the majority of scientists might be more interested in funding and fame than “truth” and…..

Second-generation p-values: Improved rigor, reproducibility, & transparency in statistical analyses

par marketingthema

Statisticians often try to come up with alternatives to p-values. Here’s a recent attempt called ‘second generation p-values’.

Verifying that a statistically significant result is scientifically meaningful is not only good scientific practice, it is a natural way to control the Type I error rate. Here we introduce a novel extension of the p-value—a second-generation p-value (pδ)–that formally accounts for scientific relevance and leverages this natural Type I Error control. The approach relies on a pre-specified interval null hypothesis that represents the collection of effect sizes that are scientifically uninteresting or are practically null. The second-generation p-value is the proportion of data-supported hypotheses that are also null hypotheses. As such, second-generation p-values indicate when the data are compatible with null hypotheses (pδ = 1), or with alternative hypotheses (pδ = 0), or when the data are inconclusive (0 < pδ < 1). Moreover, second-generation p-values provide a proper scientific adjustment for multiple comparisons and reduce false discovery rates. This is an advance for environments rich in data, where traditional p-value adjustments are needlessly punitive. Second-generation p-values promote transparency, rigor and reproducibility of scientific results by a priorispecifying which candidate hypotheses are practically meaningful and by providing a more reliable statistical summary of when the data are compatible with alternative or null hypotheses.
