  1. or it could be a type of selection bias you sometimes see in the literature.
    implicitly, the poll is really asking about the best PROMINENT actress and the sexiest PROMINENT actress. if both talent and sexiness make you more likely to be famous, then we would see a negative correlation of talent and sexiness in the prominent subset even if in the broader population they are positively correlated.
