Misunderstanding the nature of company performance the halo effect and other business delusions

To make a sound argument on the performance measures one has to formulate a process of quantifying the efficiency and effectiveness of past actions which is very subjective. If the data are based only on successful companies, there is not any comparison to show what they were doing differently to make them successful.

For example, all of the successful companies have an owner, but that is not what makes them successful.

The arguments made by him around those methodologies broadly make sense. The fallacy is that X and Y might be very strongly correlated. When researching how operations and other factors affect a company 's success, the testing needs to include companies with different success levels. In contrast Rosenzweig article takes a much more rational approach and critiques the research methodology adopted by three well reputed set of authors. In a same breath Rosenzweig stresses how dubious data and flawed findings have led to questionable findings and to a general misunderstanding of company performance. The Delusion of Rigorous Research: Some authors boast of the amount of data that they have collected, as though that in itself made the conclusions of the research valid. For example, all of the successful companies have an owner, but that is not what makes them successful. The Halo Effect. The Delusion of Correlation and Causality: mistakenly thinking that correlation is causation. Human brain can make unexpected connections using the data at hand or can even totally miss the most important relevant fact. The Delusion of the Wrong End of the Stick: getting cause the wrong way round.

Human brain can make unexpected connections using the data at hand or can even totally miss the most important relevant fact. Human brain is not a CPU in real sense and the thought processes get impacted by emotions, likings, past experiences, intelligence, education and innumerable other variables.

In a same breath Rosenzweig stresses how dubious data and flawed findings have led to questionable findings and to a general misunderstanding of company performance.

He explains that these studies, though they are more thorough with the samples, the data are based on highly on biased information, instead of getting the raw data from the companies.

Rosenzweig argues that truly lasting success outperforming the market for more than a generation never happens in business. The Delusion of Correlation and Causality: mistakenly thinking that correlation is causation. The Delusion of Connecting the Winning Dots: looking only at successful companies and finding their common features, without comparing them against unsuccessful companies. For example, all of the successful companies have an owner, but that is not what makes them successful.

They are in agreement in that both give the due importance to the quality of data to be used as input for either writing literary reviews or researching company performances. The latter cases did extensive research, but the majority of the data came from publications and articles published by journalists.

On the other hand Rosenzweig has over emphasised the impact of biases and suggested that almost every magazine or business journal out there has been lost to halo effect resulting in derivation of specific inferences on the basis of a general impression.
