Think about the last time you bought a new electrical appliance—maybe the latest smartphone, a TV with ‘intelligent’ programming or earbuds. How did you get it to work? You have four choices. Did you: (a) press all the buttons until it worked; (b) press all the buttons until you got stuck and then asked for help? (c) ask the salesperson to set it up and show you, or (d) read the manual from cover to cover before opening the box?

Think about the last time you bought a new electrical appliance—maybe the latest smartphone, a TV with ‘intelligent’ programming or earbuds. How did you get it to work? You have four choices. Did you: (a) press all the buttons until it worked; (b) press all the buttons until you got stuck and then asked for help? (c) ask the salesperson to set it up and show you, or (d) read the manual from cover to cover before opening the box?
