Reward system

The reward system in science discourages replications of other people’s work. Researchers are re-warded much more for novel contributions than for “merely repeating” the work of others. Some have argued that this reward system tends to create fragmentation and disarray in many areas of psychology, because people are rewarded for going their own way and (sometimes) ignoring progress in other closely related areas. Thus, basic phenomena will often be unreplicated. Do you think replication should be more strongly encouraged? If so, how?
