Mindfulness is Demotivating

A recent article in the Harvard Business Review mentioned a study that found meditation reduced employee motivation while having no effect on employee performance.

Suppose you conduct a new study with a sample of 200 employees at a large international company. In this study, employees were given the task to proofread a company letter to external stakeholders.

Descriptive statistics for your dataset are shown above.

Task_performance = how well the employee performed on the task on a 1-to-7 scale (7 indicating best performance).

Task_motivation = how motivated the employee was during the task on a 1-to-7 scale (7 indicating most motivated).

Experience = number of years the employee has worked at this company

Salary = employee's salary measured in $1,000s of dollars

Ability = an employee's percentile ranking on the SAT's verbal exam. It is a measure of proficiency in the English language.

Female = a dummy variable indicating the employee is a female.

Meditation = a dummy variable indicating the employee participated in a company meditation group
