Mincome was not an unconditional basic income, which is what the recent "basic income" efforts have been about. It was a means-tested social benefit program (though with perhaps lighter administrative overhead, since it was a strictly cash-benefit program with only outside income affecting grant eligibility, rather than the rather complex set of factors typical of social benefit programs.)

Most of the benefits claimed from UBI are tied pretty specifically to the unconditional aspect. OTOH, its results are interesting in that even with the reduction in benefits for outside income ($0.50 benefit reduction on each $1 of outside income), only teenagers and new mothers worked substantially less. This is interesting in considering UBI, since UBI has less reduction in incentive to work (no reduction in benefit for outside income).

Social Security isn't even approximately a basic income -- benefits are determined by tax payments (ultimately, by income earned in jobs subject to Social Security tax.)
