Science Starts with a Question, Not a Conclusion

Science is the perpetual pursuit of truth. It explores, identifies, investigates and forms models to predict future events. Models are applied to new instances and are tested against their natural environment to ensure that they are valid under similar situations. Science rests on asking questions. If science starts with a conclusion, the entire process of investigation becomes invalid.

A person who jumps quickly to a conclusion without appropriate fact finding often does so based on their personal and subjective perspective. The conclusion is more about the investigator’s personality and goals than it is about truth. The researcher projects their bias into the study and skews the results; the entire report becomes invalidated.

Starting with a question ensures that all possible outcomes are considered as an explanation. The researcher should not selectively accept and reject relevant information without ensuring they are outside the scope of the study. An accurate picture is created when all of the competing information is included in the study and used to draw logical conclusions.

The process of investigation is so important that we have developed a scientific method of balances and controls. The discovery process rigidly defines how to investigate a problem to help limit investigator bias that inadvertently seeps into the study. Ensuring scientific exploration follows appropriately methodology leads to higher relevance, validity and internal consistency of the study.

I have seen researchers push for a conclusion before designing the study. Even though they may not be aware of it, the investigator designs the entire study to justify their point.  They were not able to see the obvious and more parsimonious answers in front of them because they were perceptual blind to alternative explanations.

Whether one is conducting academic research, investigating a corporate problem, is a law enforcement investigator, or trying to replicate previous studies it is important to start with a question and not an answer. A question creates a better reflection of truth by logically moving to an unknown conclusion.

Training researchers to approach complex problems with the right mindset helps in generating better results that can be applied to predict future events. As the models change, develop, and adjust they become more accurate with each repetitive investigation. Only through openness of thought and exactness of measurement will new discoveries lead to higher performance. Each investigator should seek truth above confirmation of self-beliefs and bias.

Do you have a question or an answer? “By doubting we are led to question, by questioning we arrive at the truth.” Peter Abelard (French Philosopher)

Book Review: Philosophy 101 by Paul Kleinman



Philosophy 101 provides a broad snap shot of the major philosophical thoughts since ancient times. The book is easy to read and simplifies the theories and ideas for layman philosophers to see the depth and scope of thought in human society. It is this human thought that has pushed society to newer levels of thinking that keep humanity moving forward to new heights. 

Philosophy is considered a cultured persons hobby, a poor man’s occupation, and trivia entertainment to the masses. We fail to see that philosophy is the root foundation of science and the two cannot be unmarried. Skilled philosophers use multiple avenues to understand a problem and regularly are running against the grain of current thought. 

Despite the natural desire to arrest new thoughts in society it is the philosophers that society owes its greatest consideration. Whether we are discussing scientific principle or the very constitution of the country none of it would have been possible unless philosophical minds pondered the possibilities. 

I selected one theory, one philosophical point, and a logical-sequential function to highlight the point. The Theory of Universals tells us that everything in the universe has some type of order through connecting universals, the Philosophy of Cultures shows us that understanding our world is subjective based upon rearing, and the Scientific Method guides us in a methodology of testing our environment. 

The Theory of Universals:

The Theory of Universals states that there are universals in our world outside of mind and language. Plato believed that there were properties and qualities that can characterize our world. Some believe in forms that exist outside space and time while others believe they exist within our space and time. The example provided are the redness of a cherry and apple and how these exist regardless of whether or not someone perceives them. 

If we were to look at science and properties we can find that there are universals in terms of elements that exist and function regardless of whether or not we perceive them. As technology increases we are able to perceive universals in their more minute form and change how we define them in our minds but don’t necessary change the fundamental nature of existence. It exists whether or not we are aware of it.

The Philosophy of Culture:

Culture in the past was seen differently than it is today. Culture was part of the rearing process and created a way of understanding the world. It fundamentally changed how we view the world and how we see particular issues. Culture is embedded in our language and mental images derived from language. 

Culture is seen as collective or individualistic. In collective societies people see their duties to their social networks while in individualistic societies people feel that their duties lie primarily with themselves. Ethics and values can be culturally relative depending on the values one is reared with. Some have argued that both types of cultural vantage points can still judge right and wrong based upon helpful and unhelpful behaviors. 

The Enlightenment:

The enlightenment changes the way in which we view the world as philosophers sought to find truth in the universe. It had a profound impact on perceptions of society, government, nature, the universe, and rational thought. It changed the mystical views of the past to the scientific method we use today. 

The scientific method provided a frame work for reason and logic to analyze the world around us. The circular model is based on observation, theory development, prediction, and experimentation. As new observations and predictions occur new theories develop and existing ones are adjusted to make them more accurate.

Book Review: Brilliant Blunders by Mario Livio



Science is not as concrete as we believe it to be. What we know today as fact was once only theory. Only through the evaluation of those premises, conclusions, and so called “facts” can society continue to develop its scientific beliefs. Brilliant Blunders highlights those major miscalculations by great scientific thinkers that led to other discoveries and truths even though that was not the scientist’s intention.

Let us consider Einstein’s General Theory of Relativity that proposes objects move in relation to each other in time creating the space-time continuum that still holds true today. He also proposed a concept called dark energy. He later removed the theory calling it a mistake. A problem resulted when other researchers confirmed that it actually exists. NASA currently believes that dark energy constitutes most of our universe and Einstein was right.

Science is on its own continuum of development. Mistakes are rarely accidental and require significant learned skill to make correctly. For example, the incorrect model of DNA proposed by Linus Pauling was wrong but also helped to develop a better model of DNA. The same can be said of Darwin’s Origin of Species. The incorrect models of thinking were leaps in intellectual advancement that helped others to think differently.

Science is about putting forward a hypothesis, model and theory. They are all only explanations that can change over time as new discoveries are found. A hypothesis is tested to create a model and models are used to develop theories. A model is the physical representation of a theory and is used to generate a theory. Sometimes models are derived from a theory to test the validity of that theory.

People propose ideas and concepts and these may not always be correct. However, as they move through the scientific method they also develop affirmations and negations that can be used in other theories. Science is an additive process whereby each study helps lend support or remove support for concepts until a predominant theory takes hold. Blunders are part of that process of learning.

The book helps scientists understand that there is no such thing as a mistake as some of the greatest discoveries in the world are mistakes. Mistakes add to the body of knowledge and this body of knowledge makes its way slowly into the collective intelligence. Such knowledge is then used to advance practical concerns in the business and civilian world. If you want to understand how to make a mistake the right way read this book.
