Participation limits and the professional respondent
Caps are sold as a fraud control. They are really a control on how much one person shapes your category data.
Outline. Each heading below carries one line saying what the section has to establish. Expand each into two to four paragraphs, put at least one number or worked example in the piece that nobody else could publish, then delete this note.
The heaviest respondents are not usually cheating. They are available, and availability is not a sampling criterion anyone chose.
What a cap is actually controlling
Not fraud — concentration. One person answering forty studies in a category shapes it.
Single-source panels hit this hardest
Volume beyond natural reach means reusing the same members, and the result leaves no trace in the data.
The trade-off nobody likes stating
Caps cost the most engaged members income. Say that plainly rather than framing it as protection.
Category caps beat global caps
Two hundred studies a year is fine; twelve in one category is not. Explain why the shape matters more than the count.
Telling a member why they are seeing less
Silence here reads as a punishment. What our dashboard says and why.
Measuring concentration
The number to watch is share of completes in a category held by the top one percent of members.
