The Key Difference
Speed reading: Processing every word faster through trained techniques. Goal is full comprehension at higher speeds (350-500 WPM). Skimming: Selectively reading key sections while skipping others. Goal is getting the gist quickly, with partial comprehension (700+ WPM).
When to Speed Read
Use speed reading when: Full understanding is required. Material is complex or unfamiliar. You need to remember details. You're studying or learning. The text requires analysis or critical thinking.
When to Skim
Use skimming when: Getting an overview before deeper reading. Determining if a source is relevant. Reviewing familiar material. Finding specific information. Time is extremely limited.
The Problem with "Ultra-Fast" Speed Reading
Claims of reading 1000+ WPM with full comprehension are actually skimming. Research shows comprehension drops significantly above 450-500 WPM (Rayner et al., 2016). Elite readers like Buffett don't read at supernatural speeds - they just read consistently for hours daily.
