That implication is not logical. It is unreasonable to expect bisexuals to seek 50/50 gender split.
First, even if the actual attraction is same for both genders, it would be reasonable to expect bisexuals to seek opposite gender partners way more. Pretty much anyone who wants bio children need opposite sex partner. Pretty much anyone who don't want to deal with stigma around gayness too kuch will prefer opposite gender partner.
Second, bisexuality does not mean the attraction is same. It it fairly normal for bisexual to be attacted toany people from one gender and few from the other. It is also fairly normal foe them to have periods where they go for one gender only (either as conscious decision or not).
Besides, what did they actually look at? According to a friend, it's a lot easier to get a male date, even if you're more interested in women. How would that affect the 80% figure?
