COVID19 has exposed confirmation biases among some expert scientists. Confirmation bias occurs when people actively search for and favor information or evidence that confirms their preconceptions or hypotheses while ignoring or slighting adverse or mitigating evidence. It is a type of cognitive bias (pattern of deviation in judgment that occurs in particular situations - leading to perceptual distortion, inaccurate judgment, or illogical interpretation) and represents an error of inductive inference toward confirmation of pre-existing world-views (or hypotheses).
Professional data scientists understand that more data does NOT make better decision making. A diversity of the right smart data sets applying the appropriate conceptual framework, scenario planning and probability theory is optimal decision strategy.
Training machine learning algorithms does require huge amounts of data yet risks bad, biased, incomplete, and low quality data. While learning algorithms can add massive value in specific contexts, they can also be dangerous and create significant downside risks considering severe limitations with real-world scenarios.
Applied data science at the high level is about creating value, finding new truths and helping optimal decision making. Seasoned data scientists understand that the life of data science is experience and NOT models, statistics, math, artificial intelligence, logic or elegant computer code (although data scientists must be proficient with these disciplines). Technology and artificial intelligence are simply awesome tools that may be useful to achieve specific goals.
Professional data scientists have a number of conceptual frameworks in their mental tools kit to process raw data.
Professional data scientists are synthesizers of a wide diversity of data - turning data and information into specialized high value knowledge to achieve specific goals.
Strategic wisdom is a prudent plan to achieve one or more "big" long-term goals - consisting of a number of subsidiary medium-term and short-term goals. Developing long-term strategic wisdom is extremely difficult and required to formulate subsidiary goals. Senior data scientists help formulate strategy and modify as future reality shifts in complex environments.
COVID19 exposed many realities about modern political leadership, public health policy, and mass societal hysteria. With few exceptions (Sweden and Japan), world political leaders elected to EXPERIMENT with a draconian lockdown strategy that had NEVER been tried before.
Speed kills in data science. Faster and higher performing processors allow more efficient data science tools at reasonable cost. This opens a blue ocean of high value data science in reasonable time frames for optimal near real time decision making.
Tensor core units (TCU) outperform graphic processing units (GPU) by three (3) times. Photonic Tensor Cores have the potential to crunch massive amounts and diversities of data faster and cheaper.
Organizations with the best data scientists, quality and variety of data, and learning algorithms (AI) have a significant competitive advantage.
Decisions based on unbiased data science evidence from high quality data and learning algorithms are superior - over time - to decisions based on human intuition and reasoning alone.
Data science evidence in conjunction with human reasoning and creativity is superior to either data science evidence alone or human reasoning and logic alone.
Professional data scientists rank quantum and quality of evidence. Evidence can be strong, weak (or somewhere in between) or uncertain and incomplete.
You are a seasoned professional data scientist. You love your work and made a cool US $2.4 million dollars in income last year.
Society anoints you the new Master of the Universe. You help elect US presidents and make your clients/employers huge profits. Others want to be like you and some want to love you.
Yet you must at all costs STAY HUMBLE. Successful people act with humility and treat others with respect.
