There are different solicitation types. Not everything is Lowest Price, Technically Acceptable (LPTA). LPTA is not usually the solicitation types for anything R&D. It's more for "commodities", like tires, or bids against things with very detailed specs, like construction/infrastructure projects.
That said, it's a fair criticism that procurement specs are often poorly written, and the evaluation processes insufficiently rigorous.
