According to Daniel Schacter, there are seven fundamental ways in which our memories fail us. Schacter elaborates in his book of the same name, and now PsyBlog has produced a series of articles on each of these ‘seven sins of memory’:

1. Transience
2. Absent-Mindedness
3. Blocking
4. Misattribution
5. Suggestibility
6. Bias
7. Persistence
