Avoid committing yourself to any
strong statement. In the conclusion section, instead of interpreting your data, merely repeat the results.
Antibody to X abolishes the response is vastly preferably to Substance X is essential to apoptosis in Y cells.
Make the title as non-committal as possible: O ne title that is usually safe is The effect of X on Y-- just insert your own X and Y.
Merely conclude that The relation of X to Y needs further study. Since virtually everything needs further study, you cant be faulted.
If you are vague enough, no one will ever discover why you wanted to do your study.
Use qualifying words in abundance, such as: probably, perhaps, may, might, involve. Above all, hedge.
