what have i been saying all these years? finally. some boffins have proven that powerpoint rots your synapses.
well ok, not quite. it's linked to cognitive load theory which, as an ex-teacher, i'm only too familiar with. we can only take in and retain a finite amount of information. powerpointitis, the deadly disease which makes boring people use the worst possible built-in templates, add a squillion graphs and pie charts, embellish the dry data with 'colourful' clip art etc, is responsible for cognitive overload in presentations. basically, the slides are so busy and people are so rubbish at organising the information logically that your brain can't take it all in. so it is absolutely the presenter's fault that everyone is yawning. proven.
see, i told you about the evils of ppt some time ago. you could have listened...
