A study was done in the use of positive words in research papers.

Male scientists are more likely than female ones to publish work that describes itself as “excellent”, “unique” or “novel”, experts have found – a swagger that appears to reap dividends in respect of how often others reference the research.

This is yet another subtle way how a seemingly insignificant difference in the words men and women use could have a big impact in the long run.

“Here is another example when gender differences, probably imposed by unconscious cultural norms on both authors and editors, lead to divergent outcomes,” she said. “Because publishing itself has so much impact on career progression, this finding has significant implications. Academic processes and institutions need to pay much more attention to what gets published where, why and by whom.”
