I have recently re-learned the skin effect, and how (at higher frequencies) the outermost skin of a conductor will conduct better than the center inner-most portion of the conductor.
I have also been reading some articles regarding networking cable and have come across the mention numerous times that stranded wire has a higher attenuation...

But if the skin effect resulted in stranded cable having a lower resistance than a solid conductor, would the reverse not be true?
I have two 'truths' that are conflicting. This is the internet of course, so these truths are not 'The Truth' but are my current understanding belief.
Is this perhaps due to other effects not mentioned like inductance or capacitance within the wire?

2. Higher frequencies
At higher frequencies, conducting materials like copper experience a continuous decrease in their conducting cross section, called the skin effect. As the frequency of a transmitted signal increases, the skin effect pushes electrons outward toward the surface (“skin”) of the conductor. As the frequencies
continue to increase, the skin depth continues to decrease, so that a cylindrical, solid conducting path will become hollowed out, with electrons flowing only along the outer surface of the cylinder. In this way, the smaller and less-defined circumference of stranded conductors results in higher attenuation losses (as much as 20% higher) in stranded cables than in solid-conductor cables.
