| Tiivistelmä: | In the article three studies are reported showing that lower limit estimates (e.g. more than, over, minimum) are generally more frequent and considered more appropriate than upper limit estimates (e.g. less than, under, maximum). This is partly due to scalar properties of the number system, where lower numbers are attained before and included in higher numbers, but not vice versa. The result of this is that upper limit statements are perceived as negations, and carry more specific information about the speaker's communicative concerns. With amounts that can be perceived as small, upper limits are preferred. Lower limit statements can be used both with large quantities and as a default. |
