Yes-though also for this reason: even if there are only two options, I likely am unhappy with both and therefore can't choose either one. Analysis paralysis (indecision, procrastination & self-doubt, according to my experience/definition) is caused by dissatisfaction with both "quantity" and "quality" issues.
Quantity of choices: too many variables to take into account ("I'll never get things 'right' enough, there's too much to learn, factor in, and consider"). Complexity is exhausting to navigate.
Quality of choices: not being able to fix problem sufficiently, no matter how many or few options one is given ("I'll never get things perfect, because if I pick this then I can't have that"). In this case, wishing for more complexity to be available (in terms of a more nuanced compromise, "having it both ways") rather than being forced to make an all-or-nothing, yes-or-no decision.
I often get stuck (full of conflicting, irreconcilable, irreducable, contradictory wants/needs/drives/priorities) when either of these dynamics are at play in a situation. Of course I like having choices, yet admit complexity is actually sometimes "too much". Each person probably just has different idea of which area of life they'd like things simplified & streamlined, versus areas in which they'd like to retain the large number of offered options.
Examples: I don't drink coffee, so I don't care about how many types there are-but other people do notice & care, and would miss certain kinds if those choices were taken away. I like only one sort of (hot) tea, so when that brand is out of stock at supermarket, I'm upset, it's a big deal-yet other people might not notice or care, because that sort of tea didn't seem special or different to their tastes/senses.
Have read & recommend as interesting: Barry Schwartz's "The Paradox of Choice", Daniel Gilbert's "Stumbling on Happiness", and Leavitt & Dubner's "Freakonomics". Predicting one's future mindset is trickier (less relaibly valid) than we realize...but I digress.
