Never use a conclusion to introduce new facts or ideas. Instead, Randa Holewa, writing for Literacy Education Online, suggests painting a new picture that redefines ideas. Avoid leaving the reader confused or wondering why they read the essay. Experts agree -- avoid the temptation to start a conclusion with “In conclusion.” Never repeat the thesis word for word. Do not summarize the paper in the conclusion. Avoid the temptation to write a long conclusion. Trust that the evidence was laid out in the body. Skipping or skimping on a conclusion leaves an essay lacking.
