 ## Description
 
-Описание диагностики
+Using double negatives makes the code harder to understand and can lead to errors when the developer mentally computes False instead of True, or vice versa.
+It is recommended to replace double negatives with conditional expressions that directly express the author's intentions.
+
+## Examples
+
+### Incorrect
+
+```bsl
+If Not ValueTable.Find(SearchValue, "Column") <> Undefined Then
+    // Do the action
+EndIf;
+```
+
+### Correct
+
+```bsl
+If ValueTable.Find(LookupValue, "Column") = Undefined Then
+    // Perform action
+EndIf;
+```
