If a family perceives sons as assets and daughters as liabilities, then the family will want to, and will therefore try to, have sons instead of daughters. To challenge this gender preference, two questions need to be addressed:
1) What causes the perception that sons are assets and daughters liabilities? This calls for identifying factors causing these perceptions, and also studying whether and how these factors can be influenced to change those perceptions.
2) In the event that this perception cannot be changed – for example, if the above factors are not known, or known but cannot be manipulated – what else can be done to prevent female feticide?
The first question is about a society’s culture, and the second about its structure.
