Why do people believe that happy workers are productive workers? Well, when forming a belief, people are prone to making reasoning mistakes. There are a variety of reasoning errors (cognitive, social, motivational, etc) where we distort information, misapply effective strategies for knowing and the list goes on. I will cover three reasoning errors that contribute to this belief.
Inferring Causation from Correlation
Definition: If A and B are correlated, then there is a causal relationship between A & B. Either A directly causes B, or B directly causes A.
Just because there is a mutual relationship between two variables, does not mean that one causes the other. There might be a third variable or other factors not realized or explored.
Example: There is a correlation between physical abuse in childhood and adult violence. However, it does not mean that physical abuse experienced during childhood directly causes violent behaviors in adulthood. Rather, there may be other factors that affect the development of violent behaviors. For instance, missing variables may include a genetic tendency toward aggressiveness inherited from the abusive parent (Lilienfeld, 2010 p.13-14).
Relevance to belief: Studies have shown that there is a correlation between positive affect (feelings that reflect pleasure/engagement) and productivity (defined as job performance-meeting goals at work) (Zelensky, 2009). This doesn’t mean that happiness causes productivity. There could be other factors: co-worker interaction, difficulty of the task, good leadership and more. The mood doesn’t directly cause the individual to perform well. It may just be a factor among many that contributes to the success.
Confirmation bias
Definition: the tendency to select information that validates one’s beliefs. This may lead to biased questions to generate positive responses and elicit information consistent with one’s thinking. Simultaneously, one ignores or undervalues the relevancy of contradicting information, being more likely to look for information that confirms their beliefs.
Example: If a person believes that their childhood was positive, they are more likely to recall happy moments than negative ones. Recalling happy memories is relevant to this belief making it easier to seek confirmation, whereas negative childhood memories become irrelevant to the positive childhood position. Thus, recalling negative moments forces a person to exert more effort, which can make the thinking process feel unnatural.
Relevance to belief: When believing happy workers are better workers, one might rely too much on gathering confirming cases, where data supports the belief that a happy worker is a better performer. At the same time, one might neglect or deny cases that disconfirms it. Most importantly, one ignores cases where an unhappy worker is productive and cases where a happy worker is un-productive.
Self-fulfilling prophecy
Definition: the tendency to cause one’s anticipations/expectations by behaving in ways that fulfills the expectation. This occurs when one does not utilize all available information or recognize that there is missing information.
Example: A person might expect another to be hostile and acts in ways that provoke the other individual to respond hostilely.
Relevance to belief: If an employer instills the idea that happy workers are more productive workers, an employee might anticipate happiness as a sign of productivity, and inadvertently make more effort to be happy at work. The employee associates productivity with the efforts to be happy so he or she might behave in ways that are more productive. Ultimately the prophecy of being happy and productive will be fulfilled from the mere decision of acting upon the devoted belief. At the same time, because of these expectations and mind-frame, the employee can become intolerant towards unhappy workers, avoiding them which prevents him or her from seeing if any unhappy worker performs well.
