1. Confusing correlation with causation is not the Cardinal Sin of data science, say Gregory Piatetsky (@kdnuggets) and Anmol Rajpurohit (@hey_anmol): It's overfitting. Oftentimes, researchers "test numerous hypotheses without proper statistical control, until they happen to find something interesting and report it. Not surprisingly, next time the effect, which was (at least partly) due to chance, will be much smaller or absent." This explains why it's often difficult to replicate prior findings. "Overfitting is not the same as another major data science mistake – confusing correlation and causation. The difference is that overfitting finds something where there is nothing. In case of correlation and causation, researchers can find a genuine novel correlation and only discover a cause much later."
2. July 22, RWJF (@RWJF) will host a webinar explaining its Evidence for Action program, granting $2.2M USD annually for Investigator-Initiated Research to Build a Culture of Health. "The program aims to provide individuals, organizations, communities, policymakers, and researchers with the empirical evidence needed to address the key determinants of health encompassed in the Culture of Health Action Framework. In addition, Evidence for Action will also support efforts to assess outcomes and set priorities for action. It will do this by encouraging and supporting creative, rigorous research on the impact of innovative programs, policies and partnerships on health and well-being, and on novel approaches to measuring health determinants and outcomes."
3. Your biases, in 5 tidy categories. We've heard it before, but this bears repeating: Our biases (confirmation, sunk cost, etc.) prevent us from making more equitable, efficient, and successful decisions. In strategy+business, Heidi Grant Halvorson and David Rock (@stratandbiz) present the SEEDS™ model, grouping the "150 or so known common biases into five categories, based on their underlying cognitive nature: similarity, expedience, experience, distance, and safety". Unfortunately, most established remedies and training don't overcome bias. But organizations/groups can apply correctional strategies more reliably than we can as individuals.
4. PricewaterhouseCoopers (@PwC_LLP) explains how four key stakeholders are pressuring pharma in 21st Century Pharmaceutical Collaboration: The Value Convergence. These four: government agencies, emboldened insurers, patient advocates, and new entrants bringing new evidence, are substantially shifting how medicine is developed and delivered. "Consumers are ready to abandon traditional modes of care for new ones, suggesting billions in healthcare revenue are up for grabs now. New entrants are bringing biosensor technology and digital tools to healthcare to help biopharmaceutical companies better understand the lives of patients, and how they change in response to drug intervention." These include home diagnostic kits to algorithms that check symptoms and recommend treatments."
5. Remember 'Emotional Intelligence'? A 20-year retrospective study, funded by the Robert Wood Johnson Foundation (@RWJF) and appearing in July's American Journal of Public Health, suggests that "kindergarten students who are more inclined to exhibit “social competence” traits —such sharing, cooperating, or helping other kids— may be more likely to attain higher education and well-paying jobs. In contrast, students who exhibit weaker social competency skills may be more likely to drop out of high school, abuse drugs and alcohol, and need government assistance."
