Because of limited human capacity to gather and process information, heuristics inevitably impact on decision making to cause cognitive biases. This applies to firms’ managerial decision making and a lot of examples of misjudgment has been reported. R&D engineers may also be suffered from such biases, but very few research articles are found in this field. In this paper, we investigated whether such biases also apply to engineers by literature reanalysis and case studies. Our research suggested that engineers are suffered from several types of cognitive biases that are generally observed in psychological studies. Because of these biases, R&D engineers potentially cause wrong technological decision.
