You have too many brackets. Think of the brackets as part of the operand
itself rather than a "container" for the operand. The type of bracket
indicates the type of operand being used:
use [...] for literal values, e.g., [texthere]
use {...} for field references, e.g., {!!fieldname}
use <...> for variables e.g. <currentTiddler>
Also note that, unlike references used as arguments to macros, which use
doubled brackets (i.e., [[...]], {{...}} and <<...>>, filter operands only
use SINGLE brackets. Thus, for your use-case (a field reference operand),
omit the square brackets entirely, and only use ONE set of curly braces,
like this:
<$list
filter="[lessthan:birth{!!year}greaterthan:death{!!year}tag[People]]">
Let me know how it goes.
