The field of chemistry is highly diverse. Yet, the aggregate picture of chemists, according to this study, shows them to constitute a highly homogeneous and even gregarious group, in terms of their self-image. They see themselves as creative, as benefactors of humankind, and as craftsmen upholding a tradition of intelligent hands and preserving, even in the time of Big Science, a relatively low-tech profile. The stereotypical public image as the sorcerer's apprentices who befoul the environment and who manufacture chemical weapons is way off target. Chemists find it a caricature, it only reinforces the good conscience within the chemical community. Other conservative forces are the common language of structural formulas, a widespread phobia about mathematics, and the very length of the apprenticeship to be served. Conversely, between the mid-twentieth century and the advent of the twenty-first century, chemists displayed an impressive adaptability in the face of swift changes, regarding the tools of the trade-which the NMR Revolution had contributed to upgrade-, the funding of their activity at a much higher level, the oil crises, and the Biological Turn that affected them during that period.
