Nor in the pursuit of fame. Nor for the desire to produce an important insight into the processes of life. If anything historically has been a threat to objectivity, it has been these items. In some measure, such pursuits and desires are always present in scientists, perhaps in all of us, and in moderation, may be absolutely essential to inspire us. But good researchers know how to control the desire, how to mitigate the passion, and always have been able to do so.
Financial considerations are a newer phenomenon, particularly for biological scientists.
It has only been in the last 20 years or so that substantial consulting fees or equity interests in a new company have become widely available to scientists. It has usually been the case that researchers have hoped for a favorable outcome from their work followed by wide recognition. The world is changing, and we are not going to stop the way it does. But we can pose blunt questions. It is possible that some will not, but some may.
