<li>You are rarely the best judge of the most important material or best presentation strategy for your talk. Corollary: Give one or more practice talks.</li>
<li>Writing is much harder than you think. Corollary 1: You are not that great a writer. Corollary 2: If you don’t have a solid draft 1-2 weeks before the conference deadline, you’re starting with 2 strikes.</li>
<li>80% or more of submitted papers are rejected. Corollary: You need feedback from colleagues and outsiders to improve your paper. A poor way to get feedback is to submit the paper, wait 6 months, and get a rejection with cryptic reviews. A better way is left as an exercise to the reader. (Thanks to Mike Franklin for this particular way of looking at the “get feedback” issue.)</li>
<li>When you write up your work, remember that nobody cares what you did but only why it advances the state of the art. Edit accordingly. Corollary: edit an outline and paragraph map before you start writing. It’s much easier to rearrange/eliminate at this level than at the prose level.</li>
<li>The reviewer has 20 other papers waiting to be reviewed and is looking for a reason to set yours aside and move on. Corollary: your job is to ensure no such opening is provided—whether by unsupported statements, poor writing, rambling style, etc.</li>
<li>Your goal is not that your work gets the approval of your advisor, but the approval of the research community, as represented by the (usually anonymous) reviewers who will be evaluating your paper. Your advisor can bring her/his experience to bear and give you advice (hence “advisor”) on how to maximize the likelihood of this, but don’t mislead yourself into thinking that your goal should be to please your advisor. If the community is pleased with your work, chances are excellent your advisor will be too. Corollary: Get lots of feedback on a paper from people other than your advisor—i.e., people representative of the reviewers who’ll evaluate it—before submitting it.</li>

<b>Why Most Published Research Findings Are False</b><br />
John P. A. Ioannidis<br />
PLoS Med, August 2005<br />
<a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1182327/">http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1182327/</a><br />
<br />
Abstract:<br />
<br />
There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.<br />

We present data to show that the variability between reviewers is often the dominant factor as to whether a paper is accepted. We argue that paper merit is likely to be zipf distributed, making it inherently difficult for program committees to distinguish between most papers. We use game theory to show that with noisy reviews and zipf merit, authors have an incentive to submit papers too early and too often. These factors make conference reviewing, and systems research as a whole, less efficient and less effective.
