Your report yesterday titled ''Red-faced Abac Poll to keep lid on future surveys'' is timely. All the excuses as reported were meek and irrelevant. Only Nida Poll was almost spot-on. Dusit Poll chose not to conduct an exit poll after criticisms on it neutrality.
Most of Thailand's pollsters think they are gurus in naming a winner instead of sticking to the subject of statistics. Respectable pollsters stick to figures and nothing else.

If all the Thai pollsters had put in that notation and refrained from naming names, they would not have been so embarrassed. Only Abac's figures were outside that standard statistical deviation of 3%.
