Don't read the DailyMail for information about science.
I am not normally a defender of the Daily Mail with regard to science reporting, but in this case they did a pretty good job at reporting the design and main findings of the study being described: Ko, SJ, Sadler, S & Galinsky AD (2014). The sound of power: Conveying and detecting hierarchical rank through voice. Psychological Science, 26, 3-14.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
