Women can
contribute to SO
but choose not to!
/ SET / W&I

25-10-2013 PAGE 18
Why?
• [Gneezy, Niederle, Rustichini 2003]: women are less
effective in mixed-gender competitive environments
• [Niederle, Vesterlund 2007]: women shy away from
competition and men embrace it
⇒ To retain women we need different gamification
techniques

/ SET / W&I

25-10-2013 PAGE 19
Threats to validity
• Gender inference:
• Automated: Imprecise tooling
• Manual: Errare humanum est

• Gender swapping
• Images of other people as avatars
• Celebrities, children, porn stars…

/ SET / W&I

25-10-2013 PAGE 20
Future work…
• Roles: coders, translators, UI designers
• Similar to diff mailing lists in Drupal/WordPress
• Activity (commits) rather than discussion

• Output: code, bugs, …
• Confounding variables
• Culture/country: Malaysia – 50% of CS students
• Sexual orientation: IT might be attractive to lesbians for
the same reasons it repels heterosexual women [Landström
2007]
