Frank Furedi is a sociologist with a particular interest in parenting and families. He believes that the actions of parents are less decisive than others claim. He describes the term "infant determinism" as the determination of a person's life prospects by what happens to them during infancy, arguing that there is little or no evidence for its truth. While commercial, governmental and other interests constantly try to guide parents to do more and worry more for their children, he believes that children are capable of developing well in almost any circumstances. Furedi quotes Steve Petersen of Washington University in St. Louis: "development really wants to happen. It takes very impoverished environments to interfere with development ... don't raise your child in a closet, starve them, or hit them on the head with a frying pan". Similarly, the journalist Tim Gill has expressed concern about excessive risk aversion by parents and those responsible for children in his book "No Fear". This aversion limits the opportunities for children to develop sufficient adult skills, particularly in dealing with risk, but also in performing adventurous and imaginative activities.
